The cp command does not work for directories with large number of files in them. I don't know what the upper limit is; I could probably find out with a lot of research. Also, the mv and rm commands do not work either under the same circumstance.
It has nothing to do with the rm command. The limit is the size of the buffer that commandline parameters can be fit into. This applies to all commands(except certain shell builtins in certain shells).

I suspect that the upper limit of the number of files that it can work on is 65536. I know that it is greater than 10,000 and less than 100,000. The 65536 is a SWAG number based on 26 years of Unix shell-scripting experience.
It is a "swag number" because it's a power of two, which memory is often allocated based on. It's the maximum size of the buffer for commandline arguments per process, and system-dependent.

I cleaned up the filesystem by removing files. I had to use a for-do-done loop and remove only one file at a time; this took many hours.
You may have been interested in the xargs command. It converts things read on stdin into commandline arguments, spanning across as many executions as necessary.

The tar syntax I quoted is in the man page on my AIX box. I've been using something similar to it for more than 20 years. It works.
It works in certain situations, yes. It will probably do what the OP wants. I have my doubts that "$FILESPEC" is working the way you think it is though -- either that or AIX has a very strange implementation of tar...

rmf
RMF(1) [nmh-1.5] RMF(1)NAME
rmf - remove an nmh folder
SYNOPSIS
rmf [+folder] [-interactive | -nointeractive] [-version] [-help]
DESCRIPTION
Rmf removes all of the messages (files) within the specified (or default) folder, and then removes the folder (directory) itself.
If there are any files within the folder which are not a part of nmh, they will not be removed, and an error will be produced. If the
folder is given explicitly or the -nointeractive option is given, then the folder will be removed without confirmation. Otherwise, the
user will be asked for confirmation. If rmf can't find the current folder, for some reason, the folder to be removed defaults to `+inbox'
(unless overridden by user's profile entry "Inbox") with confirmation.
If the folder being removed is a subfolder, the parent folder will become the new current folder, and rmf will produce a message telling
the user this has happened. This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list
and returning to the current folder from which the list was extracted.
If rmf s used on a read-only folder, it will delete all the (private) sequences (i.e., "atr-seq-folder" entries) for this folder from your
context without affecting the folder itself.
Rmf irreversibly deletes messages that don't have other links, so use it with caution.
FILES
$HOME/.mh_profile The user profile
PROFILE COMPONENTS
Path: To determine the user's nmh directory
Current-Folder: To find the default current folder
Inbox: To find the default inbox
SEE ALSO rmm(1)DEFAULTS
`+folder' defaults to the current folder, usually with confirmation
`-interactive' if +folder' not given, `-nointeractive' otherwise
CONTEXT
Rmf will set the current folder to the parent folder if a subfolder is removed; or if the current folder is removed, it will make "inbox"
current. Otherwise, it doesn't change the current folder or message.
BUGS
Although intuitively one would suspect that rmf works recursively, it does not. Hence if you have a sub-folder within a folder, in order
to rmf the parent, you must first rmf each of the children.
