Where it already is. But it's a bad solution for moving text. You should just be able to click on the text and move it.
> gimp allows an arbitrary bounding box size for text layers
That's why you would probably use the x-height of the text path for one long bounding box and then add a bounding box for each letter also. There is no need for the "on click" bounding box to be the same as the in-editor bounding box. You just need to allot a small area around the text that can be clicked to move it. It's not hard, or at least it shouldn't be.

I don't know what Krita is, but you seem overly invested in this argument if you are having it so frequently that you have to preëmptively admonish it.
