To clarify. `Scrollback' here is *useful* scrollback during early boot

even if it were true (which it isnt), that is not an argument against
including a useful change that exists now and that people are interested
in.
Coloring isn't useful. If it was, it would be implemented ~16 years ago.
So anything that wasn't implemented a decade ago is not useful? Virtual
machines, software raid, fair scheduling, jumbo packets, SMT/SMP/NUMA
support, support for >4GB physical memory on x86, all fluff?
(and yes, i have implemented kernel console improvements in the past
and vga scrollback support was in fact amongst one of my first ever
Linux kernel hacks so your comment is doubly wrong.)
This `scrollback' is usual late boot / console one. If fact useful,
until first tty switch or if `screen` cannot be used. But for some
reason if scrolling region (DECSTBM) is less than whole screen, nothing
works. And if width set to odd number of columns
`stty columns $((80-1))`
whole output becomes somewhat funny.
I think by the time you get up enough to be running ill-advised commands
from shell, you are past "early boot." Your comments about scrollback
not working right if you break it are hopefully an attempt at humor.
