Most of these extra features are still pretty trivial. What does it do? Suggest entries based on recent walks, music you listened and photos. Nothing that would justify a multi-year porting effort IMHO.

And these features don't even work across devices, or rather, from what I can tell, they don't exist at all yet in the macOS Tahoe version.

Similar things could be said about for example the Passwords app. It works, it's functional, sure. But compared to apps like 1Password it's really, really barebones. You can't even change the way the it generates passwords if you need to comply with a specific policy for example.
