To do this I actually need to make some slightly more significant API 
changes than I had hoped. To make Position central, all maps, mappables 
and markers need to be able to add and remove Positions (and similar 
things). As I see it, we can say that such methods are fundamental to 
the coordination required between Bio::Map modules. I feel that I'm 
therefore justified in implementing these kinds of methods in the 
interfaces (which would allow all the downstream modules that implement 
those interfaces to work in the new system without much/any alteration).

Am I justified? Should I try harder to do it without implementations in 
the interfaces?
