GNOME-Maps is currently a libhandy app.
There is an issue raised to convert to Gtk4 and libadwaita.
As such i dont see any further reason to ship by default since you would assume it migration will occur by the time of the next LTS.
There are no replacement apps. Someone could investigate providing a web app for google maps. Raise a hand if you can do this.
Lets just drop this as a default install.
