Will the section be very long?  How long?

If it's not very long, I think the right place is in "Key Help",
perhaps as a separate subsection below it.  Also, I think which-key
should be briefly mentioned in "Display Custom", where echo-keystrokes
is described.

If the section about which-key you envision is supposed to be long and
detailed, perhaps it would be better to have a separate manual with
all that stuff, whereas the Emacs user manual should have only a short
description of the main features, and a cross-reference to the
separate manual.
