When I want to move some part of an image what I usually do, and i do it a lot, is Select pixels, Cut, Paste, Drag to new position, Anchor with one click on canvas, and repeat.
Now it's Select, Cut, Paste, change tool to Move, Drag to new position, Merge layer by clicking on a button, change tool back to Rectangle, and repeat.
I could make it faster by learning some new shortcuts though but not as before.

If pasting as a floating selection is your main (or maybe even only?) paste method, you may change the ctrl-v shortcut to be "Paste as Floating Data". Then your paste will always do a Floating paste.
Or if you need both, you could set a specific shortcut to this action and use one or the other when needed.

Wouldn't that work?

Basically floating paste is not dead. It's just not the default paste anymore when pasting to a layer.

ok nice to know, I also found out I can use the transformation tool to directly move my selection without having to Cut/Paste.
That's how I was doing it with krita already (with their move tool though).

Yeah though we were wondering if it was a good idea if the transform tools are still creating a floating selection. This may not be the most consistent behavior, and also this is quite weird with several layers selected at once (right now it merges them all into a single floating selection).
