Perhaps you're right, but I'd like to see some examples of things that
are much easier to debug from --eval than directly.

No. But if it is normal operation for your emacsclient invocation to
fail sometimes, it'd be sensible to *not* use -n and read
emacsclient's stderr output and exit code; and if it is not normal,
the moment you detect a problem you can remove the -n and try again.

This is not to say that I oppose the feature; I just don't feel it
compelling right now (but I can be easily convinced :)

Not currently, no. It returns an error for any trouble communicating
with Emacs, not because of what happens to the info exchanged between
them.
