Using the USB C spec does not necessarily push the idea of more expensive alternatives. Using USB C is less "evil" than Apple pushing the lightning connector because USB C includes [the possibility of] an analog audio signal without the need for an external DAC. This means that all that is required to use analog headphones is a USB C to 3.5mm adapter. This would not even fully be considered a "dongle" because it does not require any fancy electronics for functionality. In Host Audio Adapter mode, pins SBU1 and SBU2 directly carry an analog signal.
