Qt (and probably the KDE frameworks) resource usage is so optimized they made some lightweight DEs go "out of business".
I'm curious because I would stop using Linux if there was only GTK applications (I avoid Electron as well). I think the only exception that doesn't drive me mad is Inkscape but I don't need it. I'd rather have bloat than no features at all. GIMP has a manpage for manually drawing circles for christs sake.
If you use a modern computer you're living in pure bloat. Neofetch showing a small number of packages is placebo. "But I can make sense of everything that's installed in my machine" is placebo. Installing a 5mb window manager on top of that is placebo, and Wayfire feels lighter and faster than Sway in my tests. KDE Plasma is a full desktop environment and that's why it comes with bloat (features) included. Not using Krita because of dependencies doesn't feel like a good argument in the current state of desktop software. Security wise we have so many targets to attack that a few more packages would not make any difference.
I wish it wasn't like that too though. Let's just agree we have a very different definition to what bloat is and call it a day.

Bloated is the very last way I'd describe KDE. I was surprised to learn even Subsurface uses Kirigami; knowing Linus' opinion on weight that's some endorsement!
