Boundary Facilities from SimConnect?

Hi, are there any plans to include Boundary Facilities (air spaces) to SimConnect? As of today, this is not available (at least not documented) using the AddToFacilityDefinition function. I can see that boundaries exist in the MSFS Avionics Framework (Querying Navdata | MSFS Avionics Frameworks and Instruments) where they say:

Facilities are the heart of MSFS navigational data, and encompass all of the different types of navigational data that are available to query. The Javascript facility loading system can access 5 different types of facilities from the simulator: airports, intersections, VORs, NDBs, and airspace boundaries.

…but as I understand it, using the Avionics Framework you must be within the sim process and cannot be used by an external program.
