Some editors and implementers of the Screen Fold API attended the Second Screen WG/CG Virtual meeting to discuss this API. During that meeting that group made the following resolution for DAS WG consideration:

RESOLUTION: Drop ScreenFold.angle from the Screen Fold API first version (for DAS WG consideration)

https://www.w3.org/2021/02/24-webscreens-minutes.html#r01

This recommendation was primarily motivated by the following observations:

• need to focus on the most valuable use cases first,
• implementability considerations,
• privacy and security considerations,
• currently unresolved performance implications of exposing an angle in a CSS media query

I'd like to solicit feedback on this issue whether there are any concerns in scope-limiting the first version of this spec as proposed.

Hearing no concerns, I'd give the editors a mandate to start crafting a PR to remove the angle related API surface from the spec and align the prose with this change.

Once this spec update is complete, I suggest the group aims to publish an updated Working Draft (maybe by the end of Q1 to have a milestone) to inform the broader community of this development.
