Agreed.

For the package available on the dvd, it is unfortunately too late, but only the graphics/drm-legacy-kmod and graphics/drm-stable-kmod packages are on the dvd by default anyway. In other words, the meta-port is not included, but once a commit is merged to the 2019Q4 branch and the upstream binary packages are rebuilt, they will be available by default. Glen
