Yeah, that'd certainly be nice, though I admit that it's probably a much more complicated problem than just a simple fix. Right now the mapping routines must just automatically "fill in" the map based on your current cartography level; in order to not erase bits of the map done with a higher level, the game would have to keep track of what level each pixel on the minimap was drawn with, and know not to overwrite it with a lower level. (That or keep track, on a per-square basis on the map, what your highest effective Cartography skill was.)
Not impossible, of course, but I'd guess that it's more work than we can expect to see in a Book 2 patch. Perhaps Book 3!
