The limits are there to protect you. For a superuser account and indeed any other account, you have to ask yourself how much damage it could do by not having a limit.
I don't think that performance will come into it much unless your processing goes wild and an unlimited (or loosely limited) account starts grabbing all the system resources. This need not be a superuser either. We're had other software holding accounts grind a server to unusable. It's hard trying to escape even if you are already logged on as a superuser. Things like ps start failing and the like.
As a rule, I'd generally allow the least that I actually require.
Just my humble opinion though.

grab-account
GRAB-ACCOUNT(8) chiark utilities GRAB-ACCOUNT(8)
NAME
grab-account - add new account synchronised to remote system
SYNOPSIS
grab-account local-user source [remote-user]
DESCRIPTION
grab-account reconfigures sync-accounts to start synchronising a specified local user (which may not yet exist) from a specified remote
system, and then invokes sync-accounts once to synchronise from that source.
/etc/sync-accounts/createuser should contain a addhere line in the appropriate source section (ie, after host source). grab-account adds a
user local-user [remote=remote-user]
directive just before addhere and runs sync-accounts source.
EXIT STATUS
0 All went well.
any other
There were problems.
FILES
/etc/sync-accounts; See also sync-accounts(8).
ENVIRONMENT
See sync-accounts(8).
BUGS
There is no locking of /etc/sync-accounts so do not invoke grab-account from a script, or more than once at a time by hand. Do not edit
/etc/sync-accounts by hand and also simultaneously run grab-account.
The mechanism involving addhere is suboptimal. This should be done with an include feature in sync-accounts, so that grab-account does not
have to edit a configuration file that really belongs to the sysadmin.
