Different people were/are using it with different ideas in mind. This is
also one of the reasons why `d.erase` is not implemented in the main GUI.

This sounds good. Sometimes we are using "map coordinates", I think, but
just coordinates might be enough.

This is quite problematic one since it is not integrated with the rest of
the GUI (and it is hard to do that). I'm not sure about future of this
module but what you are saying makes lot of sense.

So, it is possible but I don't think that it is a good idea since they are
doing different things. (No strong opinion, however.)
