I prefer the hexpair form as it makes a number of DN string
manipulations much easier.  For example, issuffix needs to
check that it's splitting at a separator.  If hexpair's are
used, then it just needs to check for ',' at the split.
But if "\," and '\\' are allowed to appear, one needs to
do more checks.  As a compromise, I'd be happy if "\5C" was
used instead of "\\".
