That's like asking the alchemist to publicly publish their manuscripts.

In an ideal world, yes. However, we don't live there. Until a few years ago, GPUs and other drivers were guarded more carefully than the fucking Fort Knox.

Once you publish your drivers, you reveal a part of the inner workings of your hardware, and that's a no-no for companies.

Plus, what the other commenter said - getting hardware guys to design for a common driver interface is probably not gonna get traction.
