ketsebum has just created a new issue for https://github.com/w3c/webrtc-pc:

== Continuous ICE Gathering - Feature Request ==
## Background
The feature request is to change how browsers complete their ICE Gathering. Currently, after a short period after establishing the call, we stop gathering new candidates and move to a completed state. However, due to an event that changes network conditions for the worse, the client may disconnect from the call prematurely. While, ICE Restart solves this problem it is a slower response than preferred, and could be solved if we continued to gather new ICE candidates throughout the call.

The "walk-out-the-door" problem explains the issue that continuous ICE gathering would solve, described by these slides: https://www.ietf.org/proceedings/94/slides/slides-94-ice-6.pdf

## Other Implementations
Chromium has this implemented for their native implementations, and they use a flag to enable this:

## Request
The request here is to be able to turn on continuous ICE gathering through a similar config flag during the creation of the peer connection.
