>one can write "pthread_detach(pthread_self())" to detach yourself, whereas presumably detaching yourself via a pidfd you got from "yourself" would be a no-op

In glibc-nptl, pthread_self and _detach are functions that involve just userspace. There is not going to be a deadlock/deadlock-avoiding-noop as you envisioned.
