Sounds like 2/2 might too, does it?

Do you think any application really expects to get a SIGPIPE
when calling io_uring_enter()?

If it was about what I think I would remove lots of old garbage :)
I doubt it wasn't working well before, e.g. because of iowq, but
who knows

Yes, it was inconsistent before and now it's reliable.

Yep, that where my hesitation was coming from, but the case I had
in mind is 

1) send() -> gone to io-wq
2) close the other end
3) send() fails, probably without SIGPIPE (because io-wq)
4) userspace retries send() and inline execution delivers SIGPIPE

But I guess we don't really care. In any case, let's drop stable tag,
maybe? I don't see a reason for it, considering that stable tries hard
to preserve ABI.
