- there was no sample implementation using "putchar() with VT emulation"
- on the other hand there were simple implementation for PROM console
functions (sys/arch/sun3/dev/kd.c and sys/dev/ofw/ofcons.c etc.)
and actually it was quite simple to connect wskbd(4) to "romcons"
driver

Probably no color or inverse ops, unless PROM putchar() supports
proper escape sequence of them.

It looks:

Why not? It is not used as a partiton of fd*.
MAKEDEV is already wrong for those ports, the fd nodes probably should
, fixing kernels, or
fixing /dev nodes on existing disks (not only MAKEDEV script).
I'm afraid few developers will maintain MAKEDEV script properly,

Nowadays floppy is almost dead, so we don't have to care about

The kernels aren't broken and don't require fixing.
