What do blocks mean in a license context? 9.2.4 says basically "A blocker is considered to be matched if it is not matched" which does not make sense.
They're not a package dependency specification, so they're already disallowed by the spec.
Suggest reading the actual text of the doc; license is stated as allowing "use-conditional, any-of, and all-of groups". The point of this bug is that LICENSE definintion is dependant on any-of/all-of, which *specifically* reference blockers. No text stating "you can't block a license".
