Yes - maybe time to change those defaults, at least for routing the mic directly into the speakers. This is annoying feature for most of the apps anyway (except when you really need it for some testing, but then I'd say it's up to the application/user to turn this feedback on).
Btw, I've noted there might be some problem also with the driver as it says
