The governing principle here is comparable to the role Text-to-Speech plays for display. Device independence can in principle be provided through support of a software interface because keyboard emulation is readily available to those who need it, interfaced to all kinds of actual devices. This is parallel to the fact that audio-out can be supported by making TTS-compatible text available through a software interface, because text-to-speech is readily available. Warning: I lack any useful knowledge of the standard interfaces that keyboard emulators expect.
