Re: Call for Adoption (CfA): "Capture Handle - Bootstrapping Collaboration when Screensharing"

I object to adoption of the specification due to Issues filed in #3, #4, #5
and #6.

The API proposed for adoption is not what we agreed to proceed with at the
January WebRTC Virtual Interim Meeting.

To summarize my objections:

   1. Use case #1 is too broadly scoped by its headline: "Cross-app
   communication" is a means to an end, not a use case. The use case as
   written is “User drives a captured presentation app from a VC app” [1]

   2. Use case #1 presumes tight integration. This is too narrowly scoped.
   We should define the problem without preemptively limiting solutions. [2]

   3. The API proposed is insufficient to solve Use case #1 in common
   situations that users would like. Users shouldn’t have to choose their
   presentation program to match the software provider of the meeting they
   plan to attend, for rudimentary slide controls to work. This would lead to
   development in silos, and would be a failure to standardize something
   basic. [3]

   4. The API proposed for adoption is not what we agreed to proceed with
   at the January WebRTC Virtual Interim [5]. It is missing the important
   Actions [6] component, which through standardization won’t limit this
   critical cross-app functionality to web properties owned by the same
   corporation.

   The Actions [6] presented are the template rudimentary “next",
   “previous", “first", and “last” ones needed to advance slides from a VC (to
   drive a tab-captured generic web presentation from another generic VC tab),
   as an addition to the spec's “identification” section (which lets
   properties partner to provide the same and more through tight integration
   across specific products). [4]
