People (except of programmers :-) do not work with specs,
they work with real pieces of metal. sc(4) works out of the box
and an upgrade does not ruin the system, so it is considered better.

I was forced to deal with production system broken with 11.1->11.2 upgrade (it used vt(4) by default)
and it was not fun.

No, I will keep saying that compatibility with buggy hardware is better than lack of compatibility;
at least in case we already have the compatibility and going to lose it.

Removal of sc(4) will astonish part of our user base. We should avoid it.
