So, I just got helpful mail from AA telling me about a new program: PriorityAAccess
Details are on the web at:

_mostly_, they're just branding the existing benefits they offer elites and those traveling up front.
The substantive changes seem to be:
* new dedicated boarding queues
* benefits have been extended to passengers flying with full-fare Y tickets.
