Yes, I was referring to the way bookmarks are pushed specifically. I
am not suggesting that mercurial's push should be the same as git's
push. I just wonder whether the idea is for mercurial's bookmarks to
closely follow git's branch behavior. If that is the case and git
changes the way it pushes branches, what will mercurial do?

As for the fact that hg push pushes all branches that is one of those
things that cause a little surprise to new users. In TortoiseHg we've
added a setting called "Default Push" whose valid values are "all",
"branch" and "revision". The default is "all", since that matches
mercurial's default push behavior, but I know quite a few people who
have changed it.
