edit: not sure why this is being downvoted? not being able to define a range of port seems like a huge oversight. the forums there are not very active so I am asking here.
It's likely been downvoted because your feature request demonstrates that you're not asking about sqlite. sqlite has no server element, and therefore no ports which need using.

You're apparently not looking at the correct forums. As one of the sqlite forum moderators, i can say with some degree of authority that its forum is well-visited.
This is answered in the forums, too: https://community.fly.io/t/new-feature-every-public-port-now...
