I think this is the point that makes this discussion worth having. It
does help me to hear you state this concern in this way. I'd like to
hear/read some other opinions.

I agree. If we do decide that we force the switch then we should
immediately abandon the old code. However, I don't this should drive
the decision to do the switch with the migration.
