just a comment / question. I wonder if the use of a different extension makes
life more easy / more difficult for people using dependencies based on .mod
files to stop recompilation cascades, or other aspects of the build system. I
haven't looked carefully enough at the submodule feature to know, but maybe it
is worth thinking about. Similarly, if the .smod changes, while this reflect in
a .mod timestamp change.
There is obviously no standard requirement on this, but this gfortran feature
is very useful for those who develop & recompile large Fortran projects.
