But one may find it actually only doing 10fps reliably well. The application can easily add this label (or prefix) to its banlist and constrain it to lower resolution or lower fps. Ideally much of this problem should be solved the the media capabilities API, maybe? But what if the user agent is wrong? The application can mitigate this very quickly. The user agent would take much longer time to change and deploy.

Evidently the only way to achieve consistency on the front-end is for the front-end to create a uniform UI.

Is that possible without executing `getUsreMedia()` more than once?
