I don’t think releases that are really the same in every way except for storefront should be split out (particularly because they are usually all added using the same distribution page, where you fill out the details, and then hit ‘publish’ to all stores).
But there are heaps of cases where there’s a different label, a different release date, or other edge cases that I want to be able to store. A ‘hide digital releases’ button to get everyone off my back about it would be heavenly (do I try merge all your complicated confusing data that I don’t care about? no, because I can respect that you have different interests grumble grumble) - but I figure it’s best to wait for the upcoming redesign before requesting heaps of changes.
