guest271314 has just created a new issue for https://github.com/w3c/mediacapture-record:

== Why is start 5.3 in the specification? ==
[start(optional unsigned long timeslice) ](https://w3c.github.io/mediacapture-record/#dom-mediarecorder-start)
> 3. If at any point, a track is added to or removed from the stream's track set, the UA MUST immediately stop gathering data, discard any data that it has gathered, and queue a task, using the DOM manipulation task source, that runs the following steps:
>     1. Set state to inactive.
>     2. Fire an error event named InvalidModificationError at target.
>     3. Fire a blob event named dataavailable at target with blob.
>     4. Fire an event named stop at target. 

Why is the language of `start()` 5.3 (still) in the specification? 

- Why was recording multiple tracks _potentially of the same kind_ either not originally pursued to be specified, or attempted and not successful (technically)?

- Have we not _now_ advanced to the point where multiple tracks can be recorded?
