Well, regarding the reason: Before interfaces had no EXTERNAL attribute and
those procedures with EXTERNAL attribute had no explicit interface.

That interfaces have the EXTERNAL attribute only needed for procedure pointers.
One could think of not giving the EXTERNAL attribute to procedures declared in
interface bodies and modifying POINTER / the pointer resolution only. I'm not
sure what is cleaner and simpler.

Regarding our questions, Richard Maine (mostly) answered them. See URL in
comment #3.

  conf2(external,dimension)
is in any case wrong. It should be:
  conflict(external with implicit interface, dimension)
