Huh? Whether to offer and support variations of products (beyond price-focused tiers) has been a required decision for companies providing products/services in multiple countries/markets/regions forever. For example:
Apple has always had different global models of the iPhone, but now there are more than ever.

The App Store is similar. You can publish an app in just one store (typically the country your company is based in/where you reside), to all of the regional App Stores, or only a select. The decision would be based on variables such as development/maintenance difficulty/cost, local laws prohibiting functionality, etc.
There should be no need for such s decision from the customer perspective. Provide just the app version allowing payment via Apple Pay as well as other methods or just third-party methods in the NL App Store and a version with Apple Pay only in other countries/regions stores (assuming the app is being made available elsewhere).
From what I have seen, most developers do not create country/region-specific versions when offering their app in multiple regions. Either the compatibility/support (e.g. languages, currencies) is baked into the sole package and thus reasonably offered or that country/region is simply ignored — which seems to be the logical approach.
