Why KDE/Plasma Plugins are not supported

Hello everyone

I noticed gnomeExtensions have a relatively good support in NixOS but it’s not the same deal with plasma, as far as I see, plasma is a bit more complex and everything in it is extensible, but I guess targeting main stuff on “kpackagetool5 --list-types” would be a good start, I wanted to know, why is so? is KDE too complicated? are there other tools to replicate KDE Plugins on another system? desktop placements are a pain for me, to put all widgets on their place and install all packages every time on all sessions

What is the better way to deal with it? any information is appreciated even if not targeting main question meanwhile its not move out of plasma or live more minimalistc-ly
