Hmmm, I see the wording in the spec nearby, "For indirect calls or jumps where it is unknown at compile time which subprogram will be called [...]". I suppose this shows that the thinking in the spec is that an indirect call is something where you don't know the specific subprogram; and that means an address; and that means consumers would legitimately assume if we put a subprogram reference in then there's a direct call. Which moves me towards thinking we would need an extra/new attribute to properly describe this.
