It's clearly not all that important, or otherwise we'd have heard about
before now.
I suppose someone could do something like
wal_receiver_status_interval = 10ms
and end up silently turning the whole thing off instead of making it
very aggressive.
The mistake here is that the mathematically appropriate turn-off value
in this and similar cases is infinity, not zero.
