Is revocation really such a hard problem? Seems you could store a set of revoked tokens in memory and have a background task update it every couple of seconds. I guess it’s a separate set of infrastructure to maintain but I don’t see why it’s always presented as the thing that undermines an entire authentication scheme.
I guess if you need your tokens revoked this millisecond it’ll require an extra synchronous call on every request but that seems like a unlikely requirement. And not that any of this matter for your 10 user app anyway I guess.
