Nah, you just stick that layer in your model directory and the domain 
implementation itself somewhere else. It's not really missing, it's more that 
the tutorials, convenience components etc. all focus on small apps which don't 
need that extra layer of abstraction so much. By the time you really need the 
split to be explicit, you've probably got enough architecture for that not to 
be a problem (or if you haven't you've got bigger problems than any related to 
Catalyst :)
