I think that this might well be a great way to get walled garden address
space. We should probably emphasize that 2002: space is part of
2000::/3, and should not be treated differently by routers.
However, I'm afraid that hosts might already have rules (due to happy
eyeballs) that make 2002: useable. I hope i am wrong here.

Or anyone running DNSSEC, and I expect DNSSEC to be required for
anything working with .gov or .mil or their equivalents in other
countries.

Yes, the dns server can give out different answers to different query
origins. This interacts very poorly with DNS caches, including the ones
on hosts.
