An important characteristic of directive-based language extensions (OpenACC, OpenMP) is that the source code remains valid when the directives are just treated as the comments that they are from Fortran's perspective.  I don't see how a module compiled with OpenACC enabled would be invalid to a later non-OpenAcc compilation.
