These "posix" constructs have for a long time been documented as
*equivalent* to \d, \s and \w, with two remarks: [[:space:]] also
includes \cK and [[:word:]] doesn't even exist in POSIX.
Changing them is as bad as changing the metacharacters. Changing them to
break the equivalency might even be worse.
Also, note that perlre calls this "POSIX character class **syntax**"
(emphasis mine).
An even stronger argument is that perlre defines equivalence with
\p{...}, and explicitly mentions that these are Unicode constructs.
