I wired my whole place with 10Gb - couldn't do it in the wall (as in, hidden) so I have flat cables around the door frame and wall corners. I was willing to accept the cables, just to get 10Gb.
Not sure what we're disagreeing about, I'm not saying it's not a useful thing to have just that most people don't have it and don't intend to have it so it's not a useful spec bump for Valve to spend money on.
I'm personally planning on going through the pain to get ethernet run (luckily I have both a basement and an attic so it should be fairly easy) in my house and if I ever build new there will be whatever is the best standard at the time in the walls (and maybe some dark fiber but I'm less sure on that) but I also know I'm a vast minority of users at the same time. I'm also in a pretty big minority having a >1 gig symmetrical pipe into my house to make a 10 gig connection to my devices actually worth while.
My setup is far from my ideal one so I'm on wifi for a lot of things but I was just pointing out the business reasons they probably went with the 1 gig port, there's just not that many people who are looking for or could take advantage of a 1 gig port.
Personally I'd never go for 10g copper, just run some fibre back to your cupboard.
For APs sure, do copper for POE, but not for computers. I doubt APs will need >1G in practical places for the next decade, and I don't think 10g does poe anyway (maybe 2.5g does)

And, IMHO, it's worth it.
