I'm on KDE 6, and I don't have a ~/.kde. I think now a days, KDE uses ~/.config and ~/.local/share. Honestly, sometimes I wish the KDE Frameworks had a thing like Dconf, so apps can store their configurations inside of a database instead of barfing everything out into a ~/.config folder.

KDE 3 and 4 used a ~/.kde or similar. They moved it all to XDG-compliance with KDE 5.

Great for apps, terrible for people. It's much simpler to sync setups across machines with plain files than databases.
