Would it be possible to create a constant of type `TEAM_TYPE` in iso_fortran_env.f90 or __fortran_builtins.f90 to indicate the current team and then use that constant as the value of the missing optional argument?  This would mean that iso_fortran_env.f90 would need to be available to the compiler to process calls to the `TEAM_NUMBER()` intrinsic.
