You have a strange definition of interdependent. The majority
of my feature branches are really orthogonal; seldom on integration
there is no conflict; so it is hard for me to think of them as somehow
inter dependent. Sure, there are overlapping changes, sometimes, but
these are mostly one time resolution issues.

I am not opposed to it. If you can somehow magically create a
tool that can linearize the feature branches, more power to you. I
personally find the prospect highly unlikely; and I would like to see
some code, please, before I grant that such a thing is possible.

Sure. You can't integrate two features that fundamentally
conflict with each other. No amount of smoke and mirrors can obscure
that fundamental obstacle. This is independent of the tool set you

Strange. In all my years of using feature branches, I have never
had to consider which branch depended on what. So no, I don't think I
_have_ to remember any such thing; trust me, I would have noticed. I
have 30+ packages, and have been using feature branches since early
If you have a whole slew of features that depend on other
features, then your feature set is very different from ones I have
encountered. Dependent features do require more work; but not as much,
in my opinion, as using quilt or dpatch; but your mileage may vary.
For the most part, I just develop on each branch independently.
I compile, test, hack, compile, on each individual featre branch. And
never ever worry about what the other feature branches are like, while
Once in a blue moon (more or less) I have to deconflict the
integration branch; but mostly those are swiftly resolved issues. And
once resoved, I tend to forget about them too. All this worrying about
branch conflicts seem to be more the realm of quilt and other patch
series mechanisms; which is mostly my reason to dislike them.
