It is now up to DRM maintainers to determine if this is conceptually fine. I do see that apparently setting the opt-in option does not yet taint the kernel although Daniel Vetter suggested it might be a good idea. I guess tainting the kernel would make it easier to remove this feature in the future because it would be easier to dismiss people that claim a kernel regression due to the removal.
