And what people also don't realize is that you can run a non-compliant AP. I am 99% certain the legal framework places the responsibility on the clients and the APs (or at least the absence of a consistent one biases towards a conservative stance: i.e. not assuming it's only the AP's responsibility). If I am a massive multinational conglomerate and I ship clients that know they're in a regulated region but connect on illegal bands anyway to APs broadcasting them, then that seems to expose me to unnecessary risk. You can bet I'm going to take measures so that if this ever gets tested in court I can say "yes our software takes reasonable measures to not transmit on channels we know to be illegal in your country, your honor".
