BSD Sockets APIs compatibility with IPv4-mapped IPv6 addresses

I'm interested in whether SOCKET APIS like bind, accept, and connect can seamlessly work with a mapped IPv6 address like 64:ff9b::103.135.122.10 or any other IPv4-mapped IPv6 addresses?

I've consulted the following thread for reference and it is stated:

We do not support under-the-sockets bump-in-API (RFC 3338) and we do not support 464XLAT...

https://developer.apple.com/forums/thread/5643.

If it can support, what is above thread about?

This looks like the same issue you raised here, so I'm going to focus my replies there.
