It already exists. All their part documentation, all the dealer software, software to unlock ECUs, remove engine restrictions to get an additional 50bhp, Android apps to unlock features.. it's all widely available on dedicated websites and they've done nothing to stop it. The only thing they have ever stopped being shared is their TIS manuals which are incredibly expensive service manuals that they sell to dealers. But even in that case, they agreed to look the other way as long as the providers of the TIS manuals only let them be accessed by existing users. BMW have bundled features you can't access for a long term, and modders have been enabling them for a long time. Just look up the 328i to 330i tuning software for an example, you can use free software (bimmerlabs.com) to derestrict your engine to same power as the next model (it's the same engine, just restricted).
