My bike (well one of them) has the same. It's a racing frame, and I was always led to believe it was for the racing numbers, as mentioned by another post above
Email the manufacturer and ask them?
That gets my vote too I think. Not sure about the race number theory. When I raced in the LVRC and TLI we wore our numbers on our backs. I have seen some events with numbers shown on the frames though so by teatime I might change my mind 🤔It might be for a pump clip.
Some pumps only require one, the other end being curved to locate against a frame tube.
