My understanding is
- it's to get the allocation widely known to prevent unexpected
confliction, complication.
- it doesn't disallow use of the same bit by multiple extensions completely.

I think
- it's ok to request two or more mutually incompatible extensions
- it's ok that the server accept the client by picking one of them.
- if the client requested two or more mutually incompatible extensions and
the server acked two or more of them, the client must fail.
