I think you are overstating things. 3.5mm isn't really the standard for professional audio. Much more common is 6.35mm, RCA, S/PDIF, XLR, and USB. All of which would already need an adaptor for the 3.5mm. But I doubt I'm saying anything you don't already know.
Yes it's annoying if you already are set-up for 3.5mm, and yes I can see why you wouldn't want to use a consumer wireless audio standard for live music performance, but it hardly equates to Apple "exiting professional audio".
