This is right, the “zone” is helpful for asymmetric side-by-sides. Windows does a similar thing.

The problem is that KDE “zone” doesn’t reset even when you close all windows associated with it, which should remove all traces of zoning cause there’s no window class/name affinity anymore. But when you win-left a new unrelated window, it becomes that-sized again. There’s no “reset” except for trying to manually 50%-width it back. My workflow includes taking screenshots (automation) so this is not an option, not to mention triggering perfectionism on “is this 50 or 49.7?”. I can re-size it to be around 50, but not reset (logout helps). I’d just bind a key “like everyone else does” ©, but there’s no way to control it programmatically.

I think I’ve seen a different thread last time, but here’s a similar one: https://discuss.kde.org/t/kwin-the-state-of-tiles/18316/3

Notably, it’s not how it always worked, it just broke with an update last summer (also affecting virtual screens etc) and no one seems to bother that much, as if it was some fringe “feature”.
