On 20 Feb 2025, at 21:32, Daniel Stenberg made some helpful comments,
which I appreciate very much; he wrote:

Yes, but not exactly, I think. Using any of these is ideal iff it is acceptable
for the application to ignore "local policy" (nsswitch, ipv6 address selection).

ISTR mail from you quite a while ago that made me appreciate (after a while: I might
be a slow learner) that getaddrinfo() isn't such an abomination as I used to think
it was. 8-)

Thanks for that.

Thanks for the encouragement!

Yup.

> Happy Eyeballs v2 is enough of a challenge as it for example does not work with getaddrinfo due to its limited API.

Yup.

Yup again. I guess you have read, or soon will read, the draft, so I don't need to comment
any more extensively.

> I suspect the real complications will probably end up in the layers outside of pure DNS though.

Fourth yup.

Thanks
