Ah, the ole 'multi map' thing. Another 'unmentionable' game tries that, with horrible results.
The only way a multi-map thing would work is if when you moved beyond one map, the adjacent map automatically pops up. If the 'adjacent' map isn't made yet, you have to create it.
I disagree with not showing your position (and home) on the map. Also, when you go to an adjacent map, it should show you the direction of where home is, even if it's several maps away. If a map doesn't show those things, what good is it?
I do agree that there's no reason to have a map in the first place. All you need is to carry one thing instead of several maps: a Compass that works like a real one and that points to home. All you need to know is that the village is "that way" and your mine is "over there". You don't need a map to tell you that.
