iOS 13.5.5 code hints at Apple services bundle

Apple has long been rumored to be developing a services bundle that would combine subscription services such as Apple Music, Apple TV+ and Apple News+ into one singular pay-monthly fee, with the Financial Times most recently claiming Apple was in discussions with record labels about a new “super-bundle of media content.”
Now, references uncovered by 9to5Mac from Apple’s most recent iOS 13.5.5 developer beta suggest Apple is beginning to implement a “bundle offer” and “bundle subscription” to the management system of its existing services, seemingly confirming the rumors of an upcoming services bundle.
Subscribing individually to Apple News+, Apple TV+ and Apple Music costs just under $25 per-month as it stands, with the bundle presumably undercutting that price to offer a deal that increases user adoption across those three services.
