Category: Capabilities (Fugu)
Type: No developer-visible change
Status: Enabled by default (Chrome 111)
Intent stage: Dev trials

Breaking change: No
Enterprise impact: None

WPT details: Web platform tests will continue to test the old string "window-placement" until the flag/alias is enabled by default, then they will be updated to test the new strings.

Summary

Adds "window-management" as an alias for "window-placement" permission and permission-policy strings. This is part of a larger effort to rename the strings by eventually deprecating and removing "window-placement". The terminology change improves the longevity of the descriptor as the Window Management API evolves over time.

Motivation

The existing "Window Placement" terminology only describes one specific component of the API that allows web applications to place browser windows on target displays. It doesn't encompass the entire surface of the API described in the spec, nor will it adequately describe potential future additions to the API. https://github.com/w3c/window-placement/blob/main/EXPLAINER_spec_and_permission_rename.md
