I don't think Google was ever buy a "I don't want to use file APIs because writing the code would be hard." excuse for a security issue. I don't know what kind of exact "discussions" were possible here for "give me access to all user data, photos and everything because I don't think I want to use SAF APIs". It's like that dude in your company that will have a meltdown in PRs over his better way instead of fixing the comments and having code submitted.
Apple won't let you write into random directories past their APIs either, just because it would be too hard to use ObjC/Swift.
