Correction: The earlier answer included an unsupported availability claim. Do not rely on the iOS 16.4+ statement from the previous version of this comment.

This is a valid feature request, but StoreKit commitment/billing-plan availability must be verified against Apple's current documentation and SDK requirements before quoting exact OS/Xcode versions. The implementation direction is to expose Apple's subscription commitment / billing-plan data through the Apple native layer, generated/shared types, framework wrappers, docs, and release notes.

The maintainer implemented this in #199 by adding the StoreKit subscription billing plan / commitment types and forwarding them through the relevant package layers. For consumers, the important follow-up is to use a version that includes that release and read the documented fields rather than relying on the old periodCount-only explanation.
