>From a CS professor's viewpoint this is right. But Linux is made for
usefulness and convinience. If you want a stong design instead than
use a microkernel system (Minix, for example).

I attempted to install the FreeBSD recently. The lack of in-kenel
scrollback there hurted me hard. I do not care about VCs when system
is up and running with X11 & dmesg. But you cannot live without them

It do not buy this. You may save some RAM but I see no significant
complexity in console.c. I see a doubtful coding practice but this
is another topic.

A good idea. Implement it and send a patch to Linus.
