Forwarding to the list. Bitten by the "Reply All"
doesn't work when replying to some (a couple) users.

Pretty much, separate, yes. Just call the relevant
functions, to change values, save them, revert to
backed-up values (or standard values), etc.
This page I wrote a while ago might help with some
of the understanding:
https://www.emacswiki.org/emacs/CustomizingAndSaving
As for UIs for visually changing things, e.g.
incrementally, which you can then save (or not),
this page may help with that, at least as food for
thought:
https://www.emacswiki.org/emacs/DoReMi
Icicles also offers direct manipulation for changing
options and faces. Like Do Re Mi it lets you change
things incrementally, but you can also use completion.
https://www.emacswiki.org/emacs/Icicles
And Facemenu and FacemenuPlus can also help change
settings (which you can then save).
https://www.emacswiki.org/emacs/FaceMenuPlus
I encourage people designing and implementing more
and better UIs for _direct manipulation_ of UI
appearance and behavior (settings). These libraries
can hopefully serve as some food for thought.
Emacs has a lot you can use to do things differently,
or better, than what it offers out of the box.
Unfortunately, the Custom code (e.g. custom.el and
cus-*.el) is hard to fathom. It's not one of the
easiest interfaces for "asking Emacs" itself, as
you may have already discovered.
