They were mandated to create a scheme in isolation on a deadline, without having input either from navigation apps or from consumers, and without any requirement that web browsers or other operating systems would need to support the same scheme.

As another comment pointed out - it doesn't work. Websites and apps still integrate with a navigation product directly, rather than use this scheme. And why wouldn't they? Even if it was launched worldwide on iOS, it still is just a defined subset of any particular navigation product functionality. It also is just yet another navigation option to integrate into your platform, since the feature still wouldn't be available on desktops/Android.

Until everyone is sitting at the table wanting to work towards interoperability, the feature simply can't work. So why perpetuate a broken chooser into other markets?
