I think most framework developers unfortunately forget productivity as a key metric. Might be a bit unfair however, the lack of visual tools is disappointing.
You see a somewhat related degeneration in Redmond, where the new Windows Explorer doesn't have an icon in the address bar which is actually draggable so that a shortcut to the currently open folder can be created on the desktop or anywhere where such a shortcut can be used (think TrueLaunchBar). Now you have to go to the parent folder in order to Alt-Drag the folder to create a shortcut.
It's those little things which where smartly developed during the 80s and 90s, which "modern" developers seem not to have noticed and therefore just ignored while re-implementing applications like the Windows Explorer.

Not only has the folder address icon-drag been lost in the name of progress, so too have dozens of previously useful keyboard shortcuts, plus the core ability to re-dock Windows Start Bar onto any edge of the screen... nowadays in Win11 we are restricted to only docking at the bottom.
I think that's what Apple is attempting with SwiftUI previews in Xcode; given how long that took to not suck, I'd say it's probably harder than it seems.
