That user-space breakage is frowned upon and following that article the upstream DRM kernel maintainers outlined explicit requirements around firmware not breaking driver support. Intel engineers ended up submitting a quick fix for Linux 5.19 to still support the existing firmware while now a more adequate solution has been devised...
