If it relies heavily on unicodestring, IMHO yes.
My guess is that you mistook a comment that confirmed the base
implementation of the variable stringtype to be compatible for a
confirmation that the whole project is ready.

ansistring or shortstring, depending on {$H+}. What to do with the D2009+
change in this regard has been discussed, but opinions varied.

As said, undecided.
If I had to guess, it will end up D2009 compatible (UTF16 everywhere),
causing a similar compatibility break as Delphi somewhere.

The helpers for the types have been done mostly. Nothing else.
