That is only true in a "KDE and gnome world". There are more "environments"
out there. I specifically left out the "desktop" word since there are
environments out there where you might argue if it deserves the "desktop"
suffix. I for instance quite often fire up openbox. It doesn't have a Qt
theme platform plugin and should IMHO not aim to make one. Plasma has a
fine plugin which works wonderfully on openbox and makes qt dialogs look
fancy instead of ugly.

I let my openbox environment think that I'm in plasma by setting
"QT_QPA_PLATFORMTHEME=kde" and that thankfully still works just fine.

I do think that it's a massive shame on the plasma folks for moving this
plugin into plasma itself for supposed "better integration" which I
seriously doubt. As of this moment it's still working fine, but there is
undoubtedly going to be a point in time where the plugin only works when
some very specific plasma part is required for it to function, that will
probably make it useless on non plasma environments. They should have never
went this route and leave the framework theme as is, without plasma.. But
that's my opinion. They have theirs, they know mine and that is all just
fine. They do the work so they are very much allowed to do this. It just
