Oooh, this will lead to more phun!

Package A (module, stable) requires python-3

However, A is a dependency of *both* X and Y

Now what? Slotting? Install to both/all python prefixes? Or some other
ugly solution?

Seriously, if you *really* *really* want python-3 stable, it should:

1) NOT show up in `eselect python` to set as the default interpreter
2) NOT be a dependency of any package in stable
3) Be accessibly ONLY via the name "python-3" (or similar)

Which means, that for stable users, it will be for personal projects
only. In which case, I don't see much point in stabilizing it.
