That depends where you look. The reality is that the vast majority of track bikes won’t be ridden like that so it’s a small market to sell to. At the top of the tree where the real development happens, long and low is common, but at a price $$$$$.
I’d look at seat tube angle over TT length. The STA will be the biggest dictator of whether you can get your saddle in your desired position/setback, especially as your legs get longer. Look at Dolan’s DF4 geo. Relatively short TT but geo gives them good reach numbers to stretch out a bit
