You seem to be assuming that external test runners run the Boost
regression test suite, that's not necessarily the case. It's not
uncommon for libraries or applications that rely on Boost to proactively
build against what will be the next version to catch errors ahead of time.

Others have addressed this already, and there's plenty of material on
the webs too.

I've only felt the need to jump into this thread when positions started
to be counted, up until then I did not think it was even worth the time
discussing it. The case presented is just but one example of how
rewriting history can be disruptive; as a person who frequently uses
Boost from git, my position would stay the same even if every bot in
existence would be modified to tolerate history rewrites.

That's of course subjective, the operation exists and the tools allow
you to use it. My opinion is that using it on a public branch is
