I've never seen cable stops riveted to a frame; those are braze ons. I think sometimes they'll put a light rosette weld, but rivets?

And bottle holes are inherently different since the hole itself is reinforced by a threaded sleeve and a full weld around the circumference. Holes drilled at tube intersections are tiny and serve as vents to allow for the escape of accumulated welding gasses and drainage.

This particular frame has a bunch of indiscriminate holes in a concentrated area. Not to mention, the metal has been dented and reshaped, and this action alone is enough to reduce the integrity of the metal at that part of the tube.
