Actually it would be nice to have it if you could change on the server whether or not certain things show on it (ie Players, Vehicles, Items, etc), whether or not you can see things that aren't visible from directly above (ie things that are covered by bricks or are under interiors), the altitude of the minimap 'camera' (how high it floats above the player).
And of course whether or not it's enabled at all, and also have a clientside display toggle.
That'd be good, in my personal opinion, although others may differ.
This post isn't deliberate flamebait lul
