No basic improvements branch for 3.5 - work on tree-ssa

    And we would still welcome that.

That's not the issue. The issue is who takes responsibility for isolating and
merging those changes into 3.5 if there's a delay in the tree-ssa project or
if the experiment doesn't work out?

I don't see the advantage of having one branch that contains two major
unrelated pieces of work.
