After some updates last year, every component I could find now has a non-empty key, even if it’s not published to the library. Before that, the key was only available on components that are published to the library, otherwise it was an empty string
"", as far as I remember.
I want to use the key as a key in the dictionary and I’m wondering if it would be ok to do that? Do all components now have a unique key? Or could there still be some old files that have empty string as a key?
