And nobody will be able to stop that from happening, even if the
RBridges specification were to say "we don't support S-tags."

There's nothing in the document or proposed for the document that will
somehow cause S-tags to stop working on any network, so I don't see
what the complaint is about.

If it's purely about the wording, then let's just delete every
instance of "S-tag" from the document (to be replaced by C-tag), and
say *NOTHING* about S-tags one way or the other.

I believe that to be exactly what the original consensus proposal
said.  And, as best I can tell, it does nothing to prohibit anyone
from doing whatever he wants with S-tags.
