After reading this page it makes total sense to concentrate here the one wiki discussion. Even if it's an important factor at the Contributors proposal it is a proposal on its own, and it would make sense to reach to a conclusion about it even if the way to organize contributors wasn't defined.
I will remove the one wiki details there and simply add a link here.
I'm afraid that splitting them will make this one a blocker to the other. My current understanding is that I will be able to help with this proposal in an advisory capacity, but someone else will need to lead its implementation, including the long discussion phase with the rest of the community.
We can discuss the best way of doing this, of course.
If they are in a same proposal they are anyway a blocker of the other, so if that happens we don't lose anything. :)
I'm happy driving the discussion in both and make the connections where needed. But they are technically different things and splitting makes every discussion more manageable.
