True. Yes, there are "alternative" ways of doing this, but what we
have to face here is - console= has been used for a long time, and
it does, sometimes, bad things that can kill the system. And we,
probably, don't have that many options, we need to "fix" console=
and make it safe, while preserving the behaviour that people are
used to by now. console= is a buggy feature by now.
