Request for Mozilla Position on an Emerging Web Specification

Other information

Filing because it got some prominence in tech press and we should consider a summary position, especially to state concerns.

• Chrome platform status: Is-Input-Pending
• Facebook developer docs: Faster input events with Facebook’s first browser API contribution
• Techcrunch: Facebook makes its first browser API contribution

From my understanding this API is an attempt at providing web developers more control to improve user-perceived load-time performance, yet is a "run-to-completion violation".
