I hope not --- frankly speaking, this new stuff is horrible.
Compare how long the original Control Panel takes to open with the new "Settings App". Then compare their visual complexity. The latter takes multiple seconds to open, even has a loading screen, and yet all the controls in it are incredibly bland and featureless and conceptually simpler to render than in the old one. This is none other than a huge regression.
E.g. you have to navigate through this garbage: https://i.imgur.com/W1txUAK.png to find the one link (named "Sound Control Panel", hidden somewhere down the page) that opens the actual useful config panel: https://i.imgur.com/zDnnMPE.png
If they just made the original control panels work with HiDPI screens, there would be complaints that they've done nothing.
Slightly unrelated, but this is one of this things that annoys me the most about using gmail. Inbox by Gmail used to load instantly, there's really no good reason at all for it to have a loading screen.
It's a dead platform.
