Well, I do not know Java, but C AFAIK has no raw strings, so you have
nevertheless
to use double backslashes. Raw strings are a handy shorthand when you
can generate
the characters with your keyboard, and this asymmetry quite defeat it.

Is it decided or it is possible to lobby for it? :-)

BTW, 2to3.py should warn when a raw string (not unicode) with \u in
it, I think.
I tried it and it seems to ignore the problem...
