I can sympathize with that view, and certainly most of the heavy lifting
would come from you, same as with us and i915. However, when you put
together your hardware, an open source driver, and smart people, they
*will* scratch their itches, whether they're bugs you're not fixing or
features you're missing. Please don't underestimate and patronize them,
it's going to rub people the wrong way.

Please have a look at, say,

$ git shortlog -sne --since @{1year} -- drivers/gpu/drm/amd | grep -v amd\.com

Do you really want to actively discourage all of them from contributing?
I think this would be detrimental to not only your driver, but the whole
drm community. It feels like you'd like to have your code upstream, but
still retain ownership as if it was in your internal repo. You can't
have your cake and eat it too.
