Hey Michael, definitely, I can leave a comment.

The real reason is due to this piece of logic in sockmap:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/net/core/sock_map.c?h=v6.2#n531

And because of it, you see the same thing in (for example)
unix_dgram_connect():
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/net/unix/af_unix.c?h=v6.2#n1394

I believe it makes sense for these other socket types.
