Well that is the same argument used by some AMD team to maintain a separate out of tree hypervisor for nearly a decade. Additional to that the same argument has also been used to justify the KFD node as alternative API to DRM for compute. Both cases have proven to be extremely bad ideas. Background is that except for all the legacy stuff the DRM API is actually very well thought through and it is actually quite hard to come up with something similarly well.
