There seems to be alternatives to those proposed.

When getting "C-h k" help and you enter a prefix command, Emacs it
waiting for you to finish the command.  If you then type 'C-h', and that
has no binding it could just list what the bindings at that point are.
The use of C-h after a prefix tends to be use only to list the bindings
anyway, so if it is defined it only tells you that it is a command to
give you what you are looking for.

A less useful though more complex solution is to use tab with "C-h k"
help to first give you a list of possible completions and having to
type tab again to get help for tab itself.

The least work would be to just add a "C-h 4 C-h" command to get help
on the "C-h 4" commands available as is done in many other places.
