We would like to change the window-placement permission name to window-management to better support future improvements to windowing APIs that aren't necessarily associated with window placement. Examples could include window styling (borderless, overlay, transparency, etc) and other things affecting the behavior of the window(s). "window-management" provides a more future proof string to encapsulate all features surrounding windowing in the browser.

Ideally the spec name itself should also change to "window-management" to also support the addition of other windowing functions not specifically related to window placement.
