Hmm...
I want to do on above sample case is "required foo/bar when only gen4",
but my concern is it *always* requests "foo/bar" even though it is *not* gen4.
May be it is opposite?

Hmm... I have tried this but it was same result...
I'm not sure why it doesn't match as I expected...

I will try to post my current patch as RFC.
I'm happy if someone try it, and confirm my issue.


Thank you for your help !!
