Re: [mediacapture-screen-share] Revisit: Let getDisplayMedia() influence the default type choice in the picker (#184)

This would revisit an existing WG decision. Has new information surfaced since https://github.com/w3c/mediacapture-screen-share/pull/32 to consider it? cc @martinthomson 

> Such a functionality is easy to add 

As I recall, this was not among the concerns. The concerns, outlined in the [Security and Privacy Questionnaire](https://github.com/w3c/mediacapture-screen-share/blob/gh-pages/questionnaire.md#24-how-does-this-specification-deal-with-sensitive-information), were the security risks of sharing a web surface under attacker control: that it allows active attacks on the same-origin policy. The only hurdle is socially engineering users to select it.

This stems partly from Chrome already violating the spec's recommendations by neither implementing elevated permissions for web sources specifically nor warning users about their elevated risk. See [crbug 920752](https://bugs.chromium.org/p/chromium/issues/detail?id=920752) for context.
