Yes, I think this is a bug that should be reported to the helpful.el
maintainer(s).  Internal Emacs functions will change signatures (or
cease to exist) without warning, so they shouldn't be used by external
packages.

So I don't think there's anything to be done here in Emacs, and I'm
therefore closing this bug report.
