I'd argue that people who think they should be using caching are heavily discounting the consistency issues they will encounter (no doubt at the least convenient time), and may well end up reintroducing the same problem they're trying to solve. If you have revocable tokens accessed via an authentication lookup cache with a 5-minute expiry then you've spent a lot of time and engineering effort to have exactly the same problem as if you had non-revocable JWTs with 5-minute expiry.
