I agree with you that s/does not see/may not see/ would be more
helpful here, so I'll squash it in while queuing.

It is a good reminder for people who later inspect this part of the
code and wonder if it was a conscious design choice not to propagate
the error or just being "simple and sufficient for now", I think.
It would help them by making it clear that it is the latter, no?

Yes, all these are possible and I think writing it down explicitly
will serve as a reminder for our future selves, I think.

In my first reading, it felt to me that it was natural to interpret
that this is "even if we didn't have this loop that avoids killing
fast-export with SIGPIPE, we would notice death of fast-export by
