The doc of `default-boundp' could be improved by saying explicitly what
it means for a symbol's default value to be "void". This is not done
anywhere, AFAICT - "void" is undefined. And for Lisp, especially,
there's some risk of confusion with the value `nil'.
1. The Elisp manual is pretty good on `default-boundp', but saying
something about what "void" means would help.
2. The doc string is not so helpful - you really need to read the short
paragraph in the manual to understand it, I think. Consider beefing up
the doc string with something like what is said in the manual - it's
short and explanatory.

I think "void" should be clear enough for somebody reading the lispref
manual.

Yeah, the doc string is somewhat incomprehensible. I've now clarified
in Emacs 28.
