Precisely my point (in parallel post).

This is correct.

Yes it is the intent. The Rationale (8.3) makes this clear.

No, I don't think so.

Intriguing idea, but it is already laid down: the renaming creates a new
'slot', thus both (the original and renamed) subprograms can be (and, in the
case of an asbtract subprogram, would need to be) overridden separately.
