Given that there are people who want to remove #'bignump, should we
(provide "bignum") somewhere to give people a canonical method for
checking for bignum support??

No need; just do (natnump (1+ most-positive-fixnum)).

Then how come NEWS talks about bignump and fixnump?

Because some contributors thought that bignump and fixnump might be useful
convenience functions for Lisp programmers. They're not, but I lost that argument.
If it were up to me, I wouldn't mention these functions in NEWS or document
them, as they cause more trouble and confusion than they cure. Worrying about
the distinction between bignums and fixnums unnecessarily complicates Lisp
programmers' lives, and we shouldn't encourage it.

They're currently useful to me with the calc bignum conversion, but
won't be needed once thatʼs done, the end result will just use
'integerp'.

I agree with that sentiment.
