i work with AIX, therefore my clients are always big companies (mostly banks) with big datacentres. I have none of these fancy certifications*) but i have a project record going back more than 30 years.
Would i (or, rather my business) profit from having all these certifications? I don't think so, but i have provable experience compensating for this. I suspect that for younger colleagues the situation is different.
Personally i think this certification industry is helping nobody except themselves. Instead of finding out if (and further certifying that) a person is capable of doing certain tasks the tests simply question factual knowlege. Now, suppose you are ill and need a doctor: would you want one who can name every bone in your body correctly, but has no idea about "therapy" or one who knows how to cure patients but has to look up the name of some bones in case they are involved? A person who can name all binaries in /usr/bin without error does not necessarily have the knowledge about how to use these to achieve a certain goal - and even if he does he might not have the wisdom (read: experience) to distinguish between a good solution and a bad one. **)
Certification testing, if it should really mean something, should be done in the same way academic testing is done: you get a problem description, create a solution for it and an expert or team of experts judge what you have done. They do not give you some multiple choice tests and after testing positive on 30 of these you are a physician. Of course, this would mean that the certification business would be a lot less profitable than it is now, because it would involve actual work on the part of the certifiers. But as their intent (like any capitalistic business) is not to deliver the best possible work but to make as much money as possible this has no realistic chance of becoming reality.

*) actually this is not entirely true: i once was a certified MCSE ("Minesweeper Consultant & Solitaire Expert") because of a bet between me and a colleague from the Windows team. I was decertified 2002 because of prolongued disinterest in getting re-certified on my part. And i am still in business despite Microsoft writing me a letter which pictured my professional future without the certification in very dark colours.
**) the distinction is not good solutions work, bad ones don't because things that don't work are not solutions at all. A good solutions works AND is easy to maintain, well structured, uses the least possible resources, etc., etc. - a bad solution is a working kludge.

gnupg::revoker
GnuPG::Revoker(3pm) User Contributed Perl Documentation GnuPG::Revoker(3pm)
NAME
GnuPG::Revoker - GnuPG Key Revoker Objects
SYNOPSIS
# assumes a GnuPG::PrimaryKey object in $key
my $revokerfpr = $key->revokers->[0]->fingerprint();
DESCRIPTION
GnuPG::Revoker objects are generally not instantiated on their own, but rather as part of GnuPG::Key objects. They represent a statement
that another key is designated to revoke certifications made by the key in question.
OBJECT METHODS
new( %initialization_args )
This methods creates a new object. The optional arguments are initialization of data members.
is_sensitive()
Returns 0 if the revoker information can be freely distributed. If this is non-zero, the information should be treated as "sensitive".
Please see http://tools.ietf.org/html/rfc4880#section-5.2.3.15 for more explanation.
compare( $other, $deep )
Returns non-zero only when this designated revoker is identical to the other GnuPG::Revoker. If $deep is present and non-zero, the
revokers' signatures will also be compared.
OBJECT DATA MEMBERS
fingerprint
A GnuPG::Fingerprint object indicating the fingerprint of the specified revoking key. (Note that this is *not* the fingerprint of the
key whose signatures can be revoked by this revoker).
algo_num
The numeric identifier of the algorithm of the revoker's key.
signatures
A list of GnuPG::Signature objects which cryptographically bind the designated revoker to the primary key. If the material was
instantiated using the *_with_sigs() functions from GnuPG::Interface, then a valid revoker designation should have a valid signature
associated with it from the relevant key doing the designation (not from the revoker's key).
Note that designated revoker certifications are themselves irrevocable, so there is no analogous list of revocations in a
GnuPG::Revoker object.
