I think there are two ways of approaching this problem: one is to
consciously break backwards compatibility, introduce first-class
branches in a separate namespace from the tree, and only allow merging
between branches. This would simplify the data model enormously, but I'm
not sure it's even possible to create a sane migration tool from the
current data model to this one.
The other way, which you propose, I'm still trying to understand the
reasons for. I'm very much guessing that they can be grouped as follows:
1. Disallow the kinds of branches and consequently merges that
currently do not work correctly;
2. Simplify branch identification for users
3. Simplify merge commands
Of the above, I can empathise with points 2 and 3. But point 1 should be
solved without introducing this new feature. I'm not saying it's going
to be trivial, and I won't hijack this thread by going into details.
