I'd like to keep my M1 free from Intel software and Rosetta. But even in general I think it would be a good idea if the App Store showed which applications were already compiled for M1 and which weren't. Please send feedback to Apple at https://www.apple.com/feedback/ asking them to implement this change. Shouldn't be too hard for them to go beyond "Works on this Mac" by also saying "x86 & ARM" or "x86 only" or "ARM only".
