From an epidemiological perspective this changes nothing, but only
confirms and goes along the same line. One way or another they do build
on POSIX and inherit behaviour, good or bad.

Ah, but you should avoid "all the higher" when you most probably meant
"most, nearly all" as there is a few pieces of software which do support
it. It is however ridiculously rare today. It could be changed. Actually
add the support isn't all that hard in most places, finding all the bugs
in their intricacies is.
