While you are correct, I think they were saying it would be nice to turn on Google Maps directions and then use the same app on the same phone to do research without disrupting the current navigation.
I regularly use Maps as an actual map not just a navigation system. I’d be nice if they included a topographic map view, etc but not every app needs to do everything at the same time.
Many people have serious issues even with how stripped down everything is, so IMO as a default app loaded on every device it’s a decent compromise.
Default + website (on multiple tap) are always available, but on long road trips I use Waze.
There’s also a bunch of really nice apps for things like subway maps, trails, etc.
