I have mixed feelings about it, but I'm leaning towards allowing the
user to forget built-in facts. Ideally the built-in stuff is
implemented via the same mechanisms as the user-level stuff, so that
user-defined stuff is on an equal footing with built-in stuff.

There are various problems with that, which probably motivate in the
opposite direction, towards not allowing users to forget built-in
facts.

Not a big deal, I could go either way, so I'll let someone else make the call.
