we already have the topic:

For the design, I think we covered it enough during the Summit, and we
already have Keystone & Glance as part of composable roles, right now
the work is to implement the other services...

I don't think the plan is to backport this feature, it sounds a lot of
work, but my opinion might be wrong.

The problem is that during our work, some people will update the
manifests, and it will affect us, since we're copy/pasting the code
somewhere else (in puppet-tripleo), that's why we might need some
outstanding help from the team, to converge to the new model.
I know asking that is tough, but if we want to converge quickly, we
need to make the adoption accepted by everyone.
One thing we can do, is asking our reviewer team to track the patches
that will need some work, and the composable team can help in the
review process.

The composable roles is a feature that we all wait, having the help
from our contributors will really save us time.

Thanks for your feedback,
