I never tried to get it working on windows, but I know some people using
it there. We should just don't ignore them. Maybe it's not perfect, but
it is enough for those people.

There are regular patches for windows support, Stefan Weil is producing
builds regularly. Maybe it doesn't have all the features, but people are
making sure it basically works.

Now you want to break that because the *new* feature you want to
introduce is not supported on windows. I insist on the fact it is a new
feature simply because it was *disabled* by default. So I don't buy the
argument about "that person don't exist".

Send a call for help on that subject, give the people some time to come
with a solution (let's put a deadline), and then if nobody appears we
can definitely consider Windows support as dead. But it should not be
done arbitrary.
