"I have the resources to do it" There is always a cognitive load and time cost to a feature. Even if you don't use it. andmarios had a good point, innovation is defined as linking your phone to your desktop such that the audio out mixer volume crashes down when you get an incoming phone call on the cellphone. That's quite a cognitive load to learn about, set up, test, inevitably debug. If my wife's using my desktop and I get a call 100 feet away, what happens? She gets to debug why her phone doesn't connect to her account. It seems the "best" UI is just a physical volume control dial on a discrete amp connected to speakers, which is what I actually have. Its much more convenient than a software volume control. Also most of the "features" tend toward lowest common denominator, not universal. So a super duper copy/paste system that works DE-wide works great with things you never cut and paste in, like perhaps the GUI FAX config screen. However it doesn't talk to emacs and vi where I actually do almost all my cut and paste (or does it connect... I'll be impressed if it does, I wonder how much work it is to set up and inevitably debug) In a similar way if I get a legacy voice phone call the DE might mute my music, but is it smart enough to do so for a google hangout video chat incoming, or a legacy skype, or a hangout on my tablet not my phone... I would tend to agree, if they like it, good luck to them, although I'd never voluntarily use that kind of thing for productivity and style reasons. Just not conceptually appealing.
