Agreed. (FWIW, I specifically made sure the virtualbox-ose-additions
did not cause system crashes for 12.1.)

It just needs to be merged to the 2019Q4 ports branch. 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.
