Could you clarify which comments should be updated for SECURITY LABEL?
I don't see any references to COMMENT in RestorePass, so it doesn't look
like any updates are needed there for SECURITY LABEL either. But maybe
I'm missing something...

Good catch! This code was introduced in commit d9572c4e3b4,
which added core support for extensions. Since security labels on
extensions are not supported, I agree that the code should be
removed in master.
