As today Tesla added many locations with expected quarter they will open. Adding these data would be great.
These won’t be added to supercharge.info because they are only Tesla’s intentions and they don’t include any specific locations (to street address level). Often they take years, or get moved, or deleted. Adding these would make existing data useless.
Yes, e.g. one “expected 2020” near my place has disappeared, now.
Understandable, thank you for making the intention behind the map clear.
