Often we are struggling discovering if a code pattern in CSS or JS creating Web compatibility issues is worth fighting for (through outreach and direct contact) or just support it in the browser core engine. We have often a kind of decision process which looks like more "wet finger in the wind", aka we have an impression that we should do this or that. It would be better if we could back that up a bit more with hard data.

The goals:

1. Having hard data about Web compatibility issues
2. Evaluating if possible if it's happening in some precise circumstances (such as happening only in China or happening only with the use of this JS library)
3. Making better recommendations to the platform team on priority for implementations (new features implemented in other engines not used anywhere or used everywhere)
4. help priorities for documentation and advocacy
5. more things?
