A rebase workflow has always been problematic, in my experience. It will
cause previously published commits to be rewritten, changing their hashes,
and invalidating other branches, forks, or installations depending on them.

I also think rebasing can seriously devalue the history of a branch, by
eradicating the context in which changes had been made.

Even the got developers will recommend not rebasing public commits. I think
we should follow that advice.
