Would adding IORING_OP_{SENDTO,RECVFROM} be a reasonable first kernel
contribution? I'd like to write a program with io_uring that's listening
on a UDP socket, so recvfrom() at least is important to my use-case.

Certainly. When you hack it up, be sure to also provide a liburing
regression test case for test/ that tests the feature.

What is the benefit compared to IORING_OP_RECVMSG and
IORING_OP_SENDMSG, which already exist (and provide a superset of
sendto/recvfrom)?
