No. Mail-Followup-To does _not_ override the wishes of the user sending
the followup. It is simply a _default_ recipient list. The old de-facto
standard was
To+Cc+(Reply-To||From)
as the _default_ recipient list; the replacement is
Mail-Followup-To||(To+Cc+(Reply-To||From))
as the _default_ recipient list. The user is free to edit the list if he
wants something different---but we choose _defaults_ to save time for
the user in the common case that he's doing something predictable.
You say that some MUAs have bad list-editing interfaces: in particular,
they don't make the recipient list clear to the user. That's certainly
something to fix---no matter what the default recipient list is! You
keep bringing this up in a Mail-Followup-To context as if it were a new
problem; but the same problem existed long before Mail-Followup-To.
