If I understand the problem correctly, I think the generally accepted
way to avoid it is: "Don't commit stuff and then revert it, in a tree
that you're then going to offer for upstream merging".
So if you are working on something and you spent a day going down a
rathole, and later revert it, you can rewrite your history to look
"clean", *before* requesting that it be merged into the upstream tree.
Obviously there are issues with rewriting history after it's been made
public, but if it's in a "topic tree" which contains the development for
just one feature, and if nobody else is going development *based* on
that tree, it's normally not so bad.
