List of Piefed instances that currently defederate hexbear:
- https://piefed.blahaj.zone/ , the same way https://lemmy.blahaj.zone/ does
- https://piefed.world/, the same way https://lemmy.world/ does
- https://piefed.ca/, the same way https://lemmy.ca/ does
- https://feddit.online/, the same way https://fedia.io/ does (by the way, Fedia isn't a software, it's called Mbin, and doesn't have such code, so not sure why you're including them into your title)
- https://quokk.au/, it used to be the same when it was still a Lemmy instance
- https://piefed.europe.pub/, the same way https://europe.pub/ does

As you can see, instances defederating hexbear are instances managed by teams which were going to do so anyway, as they already did on Lemmy. I'm still waiting for an example of an instance that defederated hexbear "by mistake".
Setting up an instance isn't trivial, assuming that admins would revise the defederation list doesn't seem realistic.
There are still a few instances that federate with hexbear, showing that the 'baked in block' is just a configuration change:
- https://piefed.zip/c/news@hexbear.net
- https://piefed.zip/instances?page=9&filter=federated&search=
- https://piefed.au/instances?page=6&filter=federated&search=
- https://anarchist.nexus/instances?page=4&filter=federated&search= , which is related to https://lemmy.dbzer0.com/, also federated with hexbear
