I know they knew a lot in those days and could have dealt with the nonlinearity of air if they wished to or if there attention was drawn to it.
Actually air is nonlinear with a uneven order nonlinear connection between pressure and volumen by audio frequencies at least.
An uneven order nonlinearity produces even order distortions, this might explain our preference for single ended devices, that predominantly produces distortion of the same nature as air.
Our brain have due to natural selection been optimised, with ease, to filter out excactly the kind of distortions that dominates the medium that we are in: Air.
It would be to our disadvantage if we just by being, would get a headache due to the overload of our signal processing device between our ears.
More down to normal engineering:
Manufacturers of compression drivers have in the "recent" years introduced drivers with short throats and larger flare rates to measurebly minimize the amount of produced distortion that stems from airs pressure nonlinearity.
The discontinuities you mention are also important, not only as sources of distortion but also to nonlinear frequency responce, but that is a different story.
