we all have an optimum hip angle, and for most of us it's a bit tighter than we feel comfortable with for long periods on a road bike. But most track disciplines feature efforts that are short enough that we can tolerate a lower position. It's worth working through that on a trainer. And some core work will make a lower position more comfortable for most people.
Of course, the slammed stem style that is still current means that most people are not comfortable riding in the drops, so maybe that is where track bikes need to be anyway.
