this doesn't touch builtin-actors at all, is it worth mentioning in here? the actor CIDs will presumably be the same as existing ones and there's no need to bump them until we have actual changes?

I plan to write up a secondary doc for implementers looking to import a custom builtin-actors bundle, and test out a FIP. The overhead of that should be a lot less when there is a skeleton already in place. I will link it here, once its up 👍

Hmm.. Looks like auto-merge, merged my PR even though it failed the lint-check. I don´t think updating a markdown-file would effect that, but I will look into the lint-check failure.
