For the prompt yes. To get host candidates, I believe they would need to call getUserMedia each time, which can be visible and very intriguing/creapy to users.

Right, this is an option I like somehow.
With the particular UI illustration, it would seem weird though to expose the information and then allow the user to no longer expose it.

Not to say this would improve much the connection rate, but a connection that is providing content for a large video element visible in a page seems like a legit case. If the connection is using a TURN candidate, there could be room for optimization.

IPv6 temporary addresses are cheaper and have less fingerprint risks.
If a device could dynamically be assigned to several temporary IPv6 addresses, the risk would further decrease.
