dc(4) has the restrictions.  it doesn't look like dz(4) does, though,
and I don't find any attachments for dc(4) in vax configuration files,
even though the dc(4) manual page mentions the VAXstation 2000 and 3100.
(should I file a PR?)

$ find . -type f -name files.\* | xargs grep -E '^(device|attach).*\<dc\>'
./pmax/conf/files.pmax:device dc: tty
./pmax/conf/files.pmax:attach dc at ibus with dc_ds

$ find . -type f -name files.\* | xargs grep -E '^(device|attach).*\<dz\>'
./vax/conf/files.vax:attach     dz at vsbus with dz_vsbus
./vax/conf/files.vax:attach     lkkbd at dz with dzkbd
./vax/conf/files.vax:attach     lkms at dz with dzms

maybe dc was used with vaxen in the past, but it looks like dz is used

maybe andrew or ragge can shed some light.
