This is totally subjective, but I seem to have a vague memory of running
in to the undo limit sometime in the last few months.  It doesn't happen
very often, though, and in cases where I'm likely to use that much undo
I'm just as likely to do a VCS revert.

Increasing the default a bit probably can't hurt IMO.  Out of curiosity,
is this limit global or per-buffer?  The documentation for `undo-limit'
doesn't say, and the relevant section in the Emacs manual doesn't
clearly state it either.
