I'm not sure what policy has to do with this. If the network administrator
only wants hosts to use one IP address, then they shouldn't enable IA_TA
and IA_NA at the same time, because if they do then they could give devices
more than one IP address and will be violating their own policy.

As for the more general question, I think what actually happens depends on
the implementation on both sides. If a corporate network's policy is that
communication should only use IPv6, then Windows 98 won't work. If a
corporate network's policy is that communication should only use cleartext,
and the network blocks HTTPS, then most of today's OSes and apps will not
work or refuse to use the network. If a corporate network's policy is that
communication should only use cleartext, but the network doesn't block
HTTPS, then user devices will likely use HTTPS anyway and the user will not
be able to comply with the policy unless they choose not to connect. In all
those cases I don't think the user/employee can do much to change the
outcome (or necessarily be aware of what is happening).

Not sure what that has to do with this discussion, but... maybe you file a
feature request and they decide whether to prioritize it depending on
factors such as whether other customers are asking for it, how important a
customer you are, whether it fits with their product roadmap and strategic
goals, etc. etc.?
