The main reason to turn it off is to disable a whole lot of very poorly
tested code, and thereby improve the reliability of your warm standby
server. There might be (almost certainly are) significant performance
benefits as well. I think it'll be at least a couple of release cycles
before any sane DBA would turn it on on standbys where he didn't
positively need it.
