"This is greatly exacerbated by their typical high transconductance and when operated with the typical low current output stage bias of solid state amplifiers."You erroneously try to expolate the behaviour of BJT to all transistor types. The transconductance of a typical FET is so different from that of a typical BJT as to make your analogy invalid. The issue of high transconductance i.e. exponential rise only applies to a pure BJT not FETs. And further to that point, FETs are the most popular devices for modern class D designs, as a result, and a FET even when used in analog mode is not subject to behaviour that you describe.
