And how do we do runtime checks then? That's what GstImplementsInterface
solves. Nothing more than that. GInterface doesn't solve it, so we need
something else. What alternative solution did you have in mind?

XOverlay is not implemented by each video4linux device. Not every bktr
device implements a tuner. Not every OSS device implements a mixer. And
since we cannot know before opening the device, it simply returns "no" at
that point in time.
