If we are going to expose help-quick-sections as a defcustom, then I
don't understand why we need to change the code at all.  Is the idea
that sections will depend on the current buffer?  If so, then we just
need to add an element to the list members which will store the
major-mode for which the member is relevant.

Or what am I missing?
