If you're interested in fixing this issue, you might want to look at
the need for compatibility names so that existing DD installs aren't
broken, and so DD installs work as-is without correcting libdisk's
expectations about slice/partition names for DD disks, which is pretty
invasive, too.  Not breaking new installs by not letting users install
broken systems is the absolute bare minimum approach, and given the
late date and the lack of movement on the kernel side, I've been
advocating for it for a while.
