Yes, rewinding is exceptional.
However, when a rewind has to happen, I think most users would want to have
this feature most of the time. I think anyone who rewinds a shared branch
would hate to inadvertently throw away someone else's work. Rare is the
person who really won't care about that.
So I agree with those who say that this would be nice default behaviour. I
also don't think we need to make --force different from +refspec, mainly
because if the rewound ref turns out to have moved a simple "git fetch" will
update it and likely allow the next rewind attempt to succeed. A helpful
error message would make this plain.
I also appreciate the desire to let this stew a while before making it the
default. However, I don't think that leaving it as an option of push will
give it enough exposure. I myself want this feature, and I do rewind or
delete a branch every few months or so, but I'm almost certainly going to
forget to use this option the next time the need arises.
But if it was instead/also a configurable option I could just turn on, that
would be awesome.

For the option name, how about --match-baseref ?
