If done the way Adam Young described, with Fernet content as UUIDs,
one could in theory update from any UUID-aware provider, since the
Fernet-emitting nodes would just be writing their Fernet tokens into
the database that the UUID nodes read from, allowing the UUID-only nodes
to validate the new tokens. However, we never support jumping more than
one release at a time, so that is somewhat moot.
Also, stackforge isn't a thing, but I see what you're saying. It could
live out of tree, but let's not abandon all hope that we can collaborate
on something that works for users who desire to not have a window mass
token invalidation on update.
