Here's one with a pump on it. I think pump pegs became more widespread when bikes started getting a second set of water bottle mounts on the seat tube.

Vestigial frame tube or supernumerary top tube.
Most bicycle scientists feel the answer is inconclusive.
Either way, go ahead and use it to support a frame pump.
That's how most of us use it.
Whatever you do, don't finger it obsessively while riding.

If the pump can't be braced against something, then they are near useless. IMO.

Yes. Use to carry the pictured one on my Montello. Hit a hard bump on the MUP and it was knocked off! Almost caught in my spokes. Certainly upset my riding rhythm! Another time I hit it when using my DT's. CO2 is now the source of filling repaired innertubes or replacement sew ups.
