== What is the purpose of MediaTrackCapabilities displaySurface? ==
Hello folks, the spec currently says `getCapabilities()` should return the current [displaySurface](1) value (either `"monitor"`, `"window"`, or `"browser"`). I'm now wondering what purpose is served by exposing this capability? Is it for simple parity with `getSettings()`? I'd love to understand how web developers could use `if (videoTrack.getCapabilities() === "browser") ...` condition for instance?

Note that it was added in https://github.com/w3c/mediacapture-screen-share/pull/84

Thanks for your time!
