Reading the post above yours, perhaps it has changed in the past week.
Non-enforcement kinda removes the dedicated connotation. A contemporary example is the NEXUS or GE queues. Those are dedicated queues because they are reserved for the explicit use of NEXUS or GE members at all times. Irregardless of the time of day, the amount of traffic at an airport, etc., if groups other than those specified are allowed to queue in it, then it is no more dedicated than the AAdvantage PLT call desk.
Obviously, we have different definitions of the term "dedicated." However, until TSA actually limits the people allowed to stand in queue to TSA Pre only, it is not a dedicated line.
