FWIW, I have 6 occurrences of `help-split-fundoc' in my library
`help-fns+.el'.  But those occurrences are derived from the
`help-fns.el' code.

FWIW2, I've already updated `help-fns+.el' to use code similar
to what Juanma proposed, for `describe-mode'.  But I can no
doubt adapt both that and the `help-split-fundoc' occurrences
to whatever changes you end up making.
