Yes, I think it should be explicitly opt-in, not silently opt-out for the time being.

It is only going to change behavior if people do add a coordinate epoch in their datasets, and in that case, one can expect them to want more accurate coordinate transformations. That said adding a config option in the OGRProjCT class to ignore the coordinate epoch is trivial...
I'm glad you are getting traction with the various format groups on the topic, but that process is going to take a very long time to matriculate, and in many cases official blessing won't ever be pronounced. Let's make the behavior for applying the transformations *and* writing the metadata an explicit opt-in.
