>> That's right. Regardless that the code is written in C++ the intention is to not have any dependency on C++ runtime. The libomp.so should work fine with C applications as well as with Fortran codes those often cannot link C++ runtime.

But if profile support is enabled by default and will got into LLVM release, then people with pure C codes of Fortran codes will be surprised to see their OpenMP application depends on C++ runtime. 
E.g. if they provide Fortran redistributables with Fortran application, it won't work because of C++ runtime dependency. 
Or somebody may setup flang without clang, or gfortran without gcc, and link with libomp. 
Not sure it is immediate problem, but in length of time such things will happen.
