If not a service to validate tokens against a blacklist is again trivial and will scale to all but the top 0.1% of organizations. And it only needs to be in the blacklist long enough for the period until the token expires.
Yes, jwt is not ideal. But this talk that you should never ever use them and your service will be immediately hacked etc is silly internet bandwagoning.
For a huge percentage of services jwts are just fine. Anyone reading this, please do not over think this advice and just ship with jwts if that is what you have.
