I would have given all already-installed applications the permissions they had in the previous version of macOS. If I've been using an app for years it's a bit late to worry about it reading things that I don't want to read, and in practice showing a giant wall of permission prompts on first startup is just going to result in users clicking on Allow on all of them anyway.
