I have to think (and experiment) every single time I want to decipher one of these keyboard “shortcuts”. Why is it that only the command key (⌘) actually has the symbol printed on the key itself? And what’s up with the symbol for the option key (⌥)?

Apple and usability usually go hand-in-hand, but the keyboard shortcuts are a huge exception. Why not just put them on the keyboard? Too ugly?
