It’s a complex app. There is no reason it shouldn’t use something specific to 16.2.

If you are suggesting it could have been backported, that’s probably true, but by that logic most software has ‘artificial limitations’.

That said, from what I can tell this is part of 16.2 - I.e. it’s a new built-in app on a par with notes or photos. The store entry is just a way to get it back on the Home Screen if you delete it.
