Sometimes that's very useful.

One example is where thread has performed some logging with
its pthread_self, and you are now trying to figure out which
thread that was.

Another is when you are debugging a deadlock, and want to know
who is waiting on the given lock (thread ids of waiters are
stored somewhere in mutex_t, IIRC).
