I do not expect OpenStack upstream to solve that problem.

We may, but this is studied for each direct dependency one by one. I see
no point trying to solve indirect dependency version bounds, as it's up
to each direct dependency to test them.

What was completely wrong was, a few years from now, shipping
artificially inflated lower bounds, like, expressing that each and every
projected needed the very last version for all oslo library, which was
obviously not the case.

The lower bound testing was trying to address this. Not indirect
dependencies, which IMO is completely out of scope. However, when
testing a lower bound for a direct dependency, you may need a lower
version of an indirect dependency, and that's where it becomes tricky.
