I don't think I understand what you are saying.

Are you talking about (for example) if you use Module::Install how you can say:

...or...

...but not:

requires_any => (
  'My::Module' => 1.02,
  'My::OtherModule' => 2.33,
);

I suppose that the requires_any kind of logic could be implemented simply as a Module::Install plugin.
