Ideally, yes. But in practice dealing with very large integers is
something people don't assume naturally, and for now bignums and
fixnums don't even behave identically in Emacs Lisp.

Well, that changeset started with an attempt to fix a woefully
misleading documentation left behind, which still claimed we produce
cons cells in some situations. We must keep the master branch
reasonably well documented, because it is being used by a lot of
people. We cannot leave it in WIP state for longer than a few hours.
When code changes, documentation should follow immediately. Yes, that
means additional work, which might in the end prove more than
absolutely necessary, but I see no other way when development is done
incrementally on the master branch (as opposed to a feature branch).
Thanks.
