Not in hiera 1.0. If we started allowing \% to mean a literal % then
existing hiera data we would hit the situation where a windows path in the
data would suddenly stop interpolating. If we hold off for a hiera2 to do
these kinds of changes, then I would rather have "\" escaping, which is
much more understood and probably expected.
I was just pointing out that if we did my suggestion then we could have the
literal % in hiera 1
