If this is the case, then it should be final nail in the coffin for the
strong interpretation.

a) The model makes few positive guarantees for programs with data races
making it very difficult to predict what the program will do. The model is
primarily about saying what a program with data races will NOT do.

b) The strong interpretation can complicate distributed implementations
which compromises their efficiency for data race free programs.

So where now is the justification for going with the strong interpretation?
