I'm still a bit worried about the naming etc.
In my opinion, the thing we want to do is to do input-output
conversion for models. Models could do this themselves, but pulling
the conversion out makes things way more flexible. So... as this is
what we are doing, I would propose to choose a name that reflects
this, for example:
IModelConverter {
String toOutput(Object modelValue);
Object toInput(String requestValue);
boolean supports(Class type);
}
I'm not sure about the type paramter vs supports.

we might also consider adding IConverter.supports(Class) to make
