There is nothing in PXF that requires the routines to be intrinsic.
So I would suggest not.

Maybe.  But there are a few routines which might call internal (e.g,
non-public, subject to change) libgfortran entry points - notably in
the I/O area.  So it becomes a question of design.

Don't worry about me.  It is trivial to link my library ahead of any
system supplied libraries.

Your call.
