Actually, there seems to be a much simpler way of doing this in Fedora (and any distro more generally):
- setuptools and pip RPMs will carry the wheel inside them and drop it into ensurepip/_bundled
- the wheels will be rebuilt during every RPM build everytime *after patching*, so they will carry security patches etc.
- we will use the RPM release as the "build tag" mentioned in PEP 427 [1], so that when we e.g. fix a security bug but don't bump the version, "ensurepip --upgrade" will still see that the wheel has to be reinstalled (otherwise it'd say think the version is already there and wouldn't reinstall)
So the only thing we will need to implement will be autodiscovery of the wheels, since they will change names independently on python3 package, but I think we can do that :) From upstream point of view this shouldn't break anything, but it'd also probably not have any benefit. Would you still accept such patch?
