I don’t see full scans necessary if the same or even more data is available via reliable source. Booklet isn’t always the most reliable source (conflicting data & recording dates often have typos). With these Hyperion releases some older releases are missing recording locations but their website might still store it.
Because of potential copyright violations and potential future collaborations with labels I wouldn’t request anyone to store full sets of art (including all the pages of booklet) scanned. This isn’t necessary for identifying the correct release. I typically only include front, back, spine & medium scans.
