The motivation behind this behavior comes from the idea that if someone doesn't require rubygems, then they don't want or care about rubygems version and activation rules.  If the user *does* require rubygems, then we assume that they care about such things.

This may be a new feature.  However, I don't object it because this
issue is actually a bug and we have no other solution (There will be
another solution theretically, but not in practice in the sense that
no one write a correct patch).

But,

Your patch is not correct, unfortunately.  make test-all does not run:
