Basically, you can open some widgets inside a standalone window instead of attaching them to a bar/desktop, making them act like some kind of standalone application instead - including losing all their state as soon as their window is closed.
Actually very cool! Unfortunate that some people used them wrongly.
The only widget I've found in any way useful as a detached window like that has been the sticky note, and even there the usability is limited compared to just opening kwrite - or any other simple text editor.
It's definitely an interesting - if quite useless and potentially confusing - feature, but it makes complete sense to drop it from core and instead let it live as an extension instead, since it's quite literally just a krunner runner anyway.
