They are iterating; the Settings panel gets more settings on every release. The first version on Windows 10 was incredibly sparse.
It's also fair to say that there is a novice/expert divide -- Microsoft wants the settings panel to be as simple as settings on a mobile phone. That's great. However, occasionally I need to revert and diagnose the Wifi driver on my cheap Chinese mini laptop and I need a more powerful UI than most average people are never going to need.
At this point, I can't think of a setting that my parents would need that isn't there.
The problem isn't that settings are missing, the problem is that there are related settings in multiple, entirely disconnected locations that interact in subtle ways.
I have 4 UIs on my windows machine where I can set things related to inactivity/power down states. That's unreasonable, and nobody was confused in windows XP when those were all in one place (with an "advanced Settings" fold).
But you really only need the settings app. If you are a power user and want to mess with the individual details you hit "Additional power settings" and get the old UI. But so what?
My point was Microsoft is doing exactly the right thing here -- iterating on an existing design and keeping old software around for those who need it. Everybody seems to want Microsoft to throw out everything and instantly redesign several decades worth of software and that is ridiculous. That's not the way anyone should develop software.

I'm sure they were -- the new settings app is significantly less complicated.
