I really don't see what the issue is here. If you want a stable
branch, we can look into creating such a thing upstream, though I'm
personally of the opinion that master should remain release-quality,
and make better use of feature branches, potentially a
next/integration branch for forthcoming features, than trying to
cherry pick onto a "stable" branch. There's nothing poky's structure
provides that can't also be provided via branching policy in the
individual repositories.
