Yup.

But I also wonder if reading START-POINT with completion (with current 
branch name as default) will make sense for creating tags in all 
backends too.

I thought of Hg in particular because there was a report or two citing 
some problems with how we handle them.

And: "Mercurial offers a variety of approaches to branching, including 
“named branches”, “bookmarks” (most similar to git), “anonymous 
branches” and using clones." 
(https://markheath.net/post/using-named-branches-in-mercurial)

That's basically all I know about it.

The introduction in 
https://www.draketo.de/software/mercurial-branching-strategy, however, 
sounds very similar to Git's approach.
