Yes, totally.

I prefer doing most of the work in functions rather than macros,
because if we change defkeymap in Emacs version X+1, then packages
compiled by the user in Emacs version X will call the new function,
and thus continue to work.  I had a lot of such problems with

It seems likely that we may want to change 'custom-declare-keymap'
after getting experience from a release, so this is a real concern.
