It would be super great to go through all the status files and remove uses of
the negated variables ("unchecked", "host_unchecked", etc.) Then remove support
for them in Environment.

Even better would also be to remove all uses of "== true", "== false", "!=
true", etc.

Even best would be to then remove support for comparing boolean variables to
true and false as literal values. Only allow them as direct variable
expressions, not comparisons.

Any of this could be left to later CLs, but TODOs would be nice.

I'll just do it.
