Easy enough. That's what I did for testing of course. And I'd hope it would be always on by default eventually. The only reason why it is not on by default is because of old clients with dumb protocols.

That could be achieved with an additional criteria, like the offset's LSB value which should be pretty random.

Once Junio merges the series in a branch of its own, we could have a separate patch not in that branch that simply forces those features on in branch 'next'. People would only need to remenber not publishing repos with that version using dumb protocols.
