'Partial support' and 'Disabled by default'

[saschanaz]

But in that case, browsers that support a feature partially, not by default, and with prefix, would be marked as a d x? It sounds more complicated OoO

Chrome is moving away from vendor prefixs and set to use flags to enable in-development CSS features. It would therefore be a good idea to further discuss this.

I would be in favour of items that require setting a flag having their own notation as @saschanaz suggests.

Just added "d" as a possible value. For now it's added to a "n" and does not specify whether it's partial or not (doesn't seem as important since it won't be for all users anyway)

[saschanaz]

Good, I agree that it wont' be for all users, but at least users would be able to know that the implementation is ongoing.
