Ok, that was nonsense. First of all, compatibility flags are applicable
only for internal volumes, and we do not want to allow users creating
internal volumes, even for testing.

Secondly, your patch is right.

Thirdly, even without your patch everything works just fine, because
even though we also add this PEB to the used tree, we'll never ever use
it, so it will not cause problems.

Thus, I'll just apply your patch, thank you.

And not need to send it to '-stable'.

They actually seem to work fine.
