Adding extra config to turn on your feature isn't ideal, correct. However, all
minor revision changes should be backwards compatible or you break systems. As
I understand it, this is the way Exim updates have always happened. If we were
moving from Exim 4 to Exim 5 rather than from one version of Exim 4 to another
then yes, it would be ok, but we're not...

The majority of people don't expect upgrading from 4.69 to 4.70 to require them
to change their configuration, for things to continue to work as normal.
