Hoe about this: if you decide to delete data that the OSMF has decided 
not to accept, look at the history and only delete what's necessary. 
There's no need to make it harder on ordinary mappers who don't care 
about the license change. This should be treated similarly to an import: 
if you're not willing to merge the existing data, don't do it. If your 
change results in the deletion of tags like highway=traffic_signals and 
lanes=* that have been added by CT-agreeing mappers, you're doing it 
wrong. (Oh, and don't forget to change the number of lanes properly if 
you're changing a dual carriageway to a single carriageway or vice 
versa. Enough mappers fail to do this even when making ordinary edits.)

In short, if you're not willing to fix any damage you create, don't 
delete non-CT data.
