Apple implemented a similar change for the EU App Store earlier this year to comply with the Digital Services Act (DSA), a regulation that now requires app developers to provide their “trader status” to submit new apps or app updates for distribution.
For the record, Apple notes that the DSA requirements only impact developers distributing through the App Store, not through alternative distribution [1].
