Because reception of process output is not necessarily a frequent
event, so we want to be sure the user had enough time to see the
message.

Post command hook is called much more frequently.

I see no reason.  If the mechanism of disabling such a filter will
work reasonably well, the sleep will annoy a few times, and then go
away.

I understand that it pissed you off, but the situation where it
happened will be resolved by the automatic disabling, so your past
annoyance doesn't need to affect anything else.  IOW, I think you are
over-reacting here.
