It's also requested now and then in the context of auditing and

is introduced to manage the tradeoff, it should be defaulted to 'on'.
Alvaro's original submission specified that the feature defaults to "off".
Since there's no use-case for it unless you've installed some third-party
code (eg an external replication solution), I think that should stay true.
The feature's overhead might be small, but it is most certainly not zero,
and people shouldn't be paying for it unless they need it.
Agreed, that's why it stayed 'off' in my version too.
