BOTH airlie and vetter had the same issue with this latest rfc. The difference is that airlie wasn't being circumspect.
Take a look at the ml and read through the very brief thread (six or seven missives, I behave).
Maybe bridgman is aware of something that's not apparent to me, but the fact that agdf said (AIUI) that the hal had to stay because otherwise they just don't have the resources to do validation as well, means that the most we can hope for, in the near future, is an Android-type situation. Over time the delta will get smaller (assuming they work to improve the drm abstractions do they more closely resemble what AMD needs from them) but that core HAL may not go away for awhile.
Of course, it's still very early days. Maybe this really is a miscommunication. Maybe they can work on their validation "framework" as they diverge from the HAL?
Take a page from bridgman and try to be classy. You can get the same info across without causing misery.
