Please, add built-in support for .bullet files!

Blender uses the Bullet Physics API for physics simulation, and it blows my mind why in 2019 still there is no built-in support for importing/exporting .bullet file.

Long ago there was BGE, and an old and simple add-on that relied on BGE for exporting physics data (rigid bodies and constraints) to a nice and simple .bullet file.

But then everything changed when the Blender 2.80 attacked... BGE will not be supported anymore.

Exporting .bullet file should be the official way to export physics data, because Blender uses that engine.

UPDATE

I just found out that Blender 2.80rc doesn't support Compound Shape objects. Really?! Why? This is concerning me for different reasons, and it is also a performance issue. Does anyone think that emulating this low level bullet functionality by forcing more rigid-bodies and constraints into the simulation is a good idea or export-to-game-engine friendly?
