This is a quirk of the conversion. We have to patch up several tags
post-conversion, which patches up their notes, but that happens after the
full conversion is done. Notes are just 1 long linear branch, which ...
well, is unfortunate. So essentially every update to the repo changes the
last couple hundred of hashes for the commit notes objects/tree/DAG/linear
train. They always need to get force-pushed upstream and you always have to
re-fetch quite a bunch of them.

This will all cease with the final transition, obviously.
