A user ... not wanting a particular command to be excluded ...
for whatever usery reason.  How to override the exclusion?

Sure, people can always rewrite the code we provide.  That's not
what is generally meant by user control over commands, in Emacs.

Optionally completely on or completely off is not what I'm
getting at, either.

We are talking about providing declarations at the individual
command level (and possibly at the file/package/mode level).

Users should be able to change that behavior for an individual
command, just as you can declare it for an individual command.
That's what advice is for: tweaking an individual function.
Users should not need to redefine commands, if we can give them
a better way.
