There are rules currently - basically that the only thing allowed on the Fortran side is to pass an assumed-rank dummy as an actual argument to another procedure. Are you saying that the scope of the TR needs to be expanded to specify ways for things like this to be used in Fortran? Beyond the rank remapping already allowed for pointers? Note that the main purpose of adding this feature was for MPI-like interfaces, where the only objective was to pass the object to a C function and give the function tools to correctly interpret the object.
