With what setting of max_standby_streaming_delay? I would rather
default that to -1 than default hot_standby_feedback on. That way
what you do on the standby only affects the standby.

A default that allows anyone who has a read-only login to a standby
to bloat the server by default, which may require hours of down
time to correct, seems dangerous to me.
