Will all of these changes add up to it being impossible to make a
device NOT be recognized as gpt once it has had gpt on it?

It's typical to dd some zeroes to the start of a volume to clean out
old info, but if geom is going to aggressively ressurect a purposely
-nuked GPT based on the backup info (which is hard to find and dd over
by hand) this is going to add up to a lot of frustration for those of
us who have to frequently work with regenerating sdcard and CF images.
