Nit: s/Equals/Equal/ (x.Equals(y) reads like proper English, x.NotEquals(y) does
not but x.NotEqual(y) sounds fine again)

Done.

The fact that "obsolete" does not match any of the extension ids is a bit hack.
Maybe better add another predicate method for this test which simply returns
true?

Done.
