The "propagate if it does not break the verifier" is a bit weird to me: it means that a we would propagate a concat with dynamic shape, even though the metadata would be incorrect, just because a static verifier can't catch it is incorrect.

Also this seems to acknowledge that it is OK to drop the metadata, so It should just always be OK to drop it...
