Indeed. These options can be set from the command line when building
the image, so the distro wrapper scripts can just en/disable the
features they desire.

As for maintenance: indeed, lack of maintainership generally also
means lack of testing coverage, and if something breaks, we won't
notice, and if we do, we may not be able to fix it without running the
risk of breaking something else.

So at some point, these drivers will be removed rather than kept alive
by the core team unless someone steps up.
