We'll still have squeekers, they'll just go from whining about wanting their one-off 1945 superplanes to wanting stuff like warps to and from the combat zone (since the planes are so slow and its no fun to fly a whole extra five minutes to get to a fight) and two-seaters with autogunners to watch their backs (since all they can do with such slow planes is go around in circles), and suped-up 1919 what-if planes (because 'the war didn't officially end until the treaty was signed in 1919, so we should have this').
