Well what I've described is the fundamental reason why that shouldn't
happen and why everybody should agree that it shouldn't happen.

At the point where an apparent limitation or constraint in one WG's
protocol is discovered by another WG, the latter WG should then consult
with the first WG on how to solve the problem that would be consistent with
the first WG's protocol and architecture.

If the behaviour doesn't comply with RFC 8200, it isn't IPv6 anymore.
Instead it is a proprietary and unofficial variant of it.

There's an RFC about this sort of thing. It also applies to different IETF
WGs.
