LGTM1 - aligning with other browsers on this (and the spec!) is good.
0.0002% is indeed low.

<https://w3c.github.io/mediacapture-screen-share/#dom-mediadevices-getdisplaymedia>
Summary
Allowing getDisplayMedia() to be triggered without a user activation
could be abused by malicious websites. To protect users, the spec was
changed[1] to require user activation, and we are now following
through in the Chromium implementation.

Risks
Interoperability and Compatibility
Firefox and Safari's implementation already require user activation
for calling getDisplayMedia().
As websites already handle getDisplayMedia() returned promise
rejection for other cases such as user cancelling the browser prompt,
I believe there’s no compatibility risk.
We still added[1] a UseCounter[2] to track use of this feature and
noted near zero usage.
