While not having a factually incorrect commit message is a great
start I still don't think we want it. For one there is no actual
use case for the actual semantics, so why add it? Second it still
needs all the proper per-driver opt-in as these sematncis are not
defined for all out protocols as I've already mentioned before.
But hey, maybe Kent can actually find other storage or file system
developers to support it, so having an at least technically correct
patch out on the list would be a big start, even if I would not expect
to Jens to take it in a whim.
