OK, I'll investigate that. I'm confident we can easily have .xz back in a
way or another.

If I'm not mistaken, current aggregator has never guaranteed anything about
provenance and does some dependency resolution against *all* repos already.
I'll work on an example to prove me wrong or false and report the results
and example. That will either strengthen or invalidate this argument.

Nothing indeed, unless some other requirements enforces a specific version
of the artifact in its dependency chain. But as mentioned, I believe it's
the same for current aggregator already. More details to come next week.

 They're both relying on p2 director so there shouldn't be a too big
difference; but we'll diff the output.

I agree. However, I think there are still technical questions that need an
answer before we require Planning Council to voice an opinion.
