If two technology changes is an excuse for unimplemented features, that sounds like some pretty unusable software to me. "The rest is details" was exactly the problem the parent was referring to. "Desktop search is finally quick"--I think most users would want it to be quick first, and then the devs can do whatever "technology changes" they want.
I tried to like KDE, but every time I tried it, one of the first apps I tried would immediately crash. Plus it's default looked like a bad copy of Windows XP, which was a bad copy of the Mac, so it looked really bad. (That was a long time ago.) Unfortunately, GNOME looked nice, but had no features, so I just gave up and went to a bare window manager and realized I have no need for anything a DE offers. Then the problem became that sawfish became unsupported, and nothing else had the same customizability.
Actually it was always quick, just the indexing sometimes would be a little resource intensive.
I’m not going to claim KDE didn’t deserve that reputation in the past. The architectural changes are to blame, but they weren’t frivolous. You can’t build on shaky foundation.
I also think it’s not fair to criticize it based on some snapshot from the past. You’ve seen the beta. It’s really good now!
