This is incorrect. You forget to take into account that ATC
doesn't need to talk to you at all. That in itself is restrictive. If
ATC tells you "Aircraft calling for Class B clearance remain outside
of Class B airspace", it is restrictive, even if they do not
acknowledge
you directly. If ATC doesn't answer your call, you are to remain
outside of Class B until they do. If they don't answer, too bad.


Answering you isn't enough, if ATC does not clear you into Class B airspace
you are to remain outside.
