If you simply set a value for a key that already exists, the order
should not be changed. I think this is intuitive.

You could ask the same question about dict. I think that is not an
option. Why should you want odict behave different than dict?
I still believe that the concept of an "ordered dictionary" ("behave
like dict, only keep the order of the keys") is intuitive and doesn't
give you so much scope for ambiguity. But probably I need to work on an
implementation to become more clear about possible hidden subtleties.
