That was my point. You can easily add validation checks to JWT. Just invalidate tokens issued before a certain time.

How do you do it without the service going into some sort of a database to check if there's a certain time for which all tokens older than it should be invalidated?

Well you don't ;-)

If you stick to OAuth and OIDC you have the option to validate the tokens against the userinfo and introspect endpoints, but that's, just another "database"
