Are you sure it doesn't? Google Maps on Android does, for me.

Zoom into some location you've never looked up before, in some country you haven't been to. Turn on airplane mode. You can pan around and the nearby areas will still be there. Zoom out, and previously cached tiles will still be available. Go to some other part of the world, and a coarse resolution version of their polygons should still be visible.

I think as of a few years ago, it also auto-caches tiles along a navigation route, but I can't find the announcement stating that anymore :(
