There isn't a set policy on this as yet but widescreen status here is generally based on the game using the extra space with the correct aspect ratio, so as on WSGF a game that stretches or pillarboxes is considered false.
The steps needed to achieve stretched/pillarboxed widescreen resolutions are still provided where applicable, and in the case of pillarboxing this is especially useful since it looks much better than scaling a normal 4:3 resolution.
As for the cloud saving issue it looks like that was fixed before I got to it; you're right, they should only be specified if available on those services, so if you can't buy the game there simply leave its parameter blank (unknown will still show the line).
