Yep, didn't test because I didn't expect any faliures. Was hoping too much for protobuf to be just happy dandy "nothing to see here". :D

@gferon I added some non-trivial logic here. A pair of eyes and a brain that has been covid free for more than a week would be welcome!

LGTM! I already gave this a spin with the PNI work underneath and this seems to cause no issues at least.
