It would be useful to skip prompting for window-management when calling getScreenDetails(). Some ways in which this would be useful include:

• Maybe the app does not actually need to window-place if there's only a single screen?
• Maybe the app is making other decisions based on this information, such as deciding to go full-screen or to trigger Picture-in-Picture.
• Maybe the app prompts the user to record all screens (using getDisplayMedia), and only needs getScreenDetails() to figure out how many screens there are.

It seems to me that gating by window-placement might be more appropriate for "write" operations than for "read" operations.

One possible counter-argument might be fingerprinting concerns.

Wdyt?
