Domains are supposed to a logical construct that restricts the accepted values for a data type (it's in the name "domain"). Expanding that into a general "column definition macro" seems outside its scope. For example, what would be the semantics of this when such a domain is a function argument or return value?

Considering how difficult it has been to maintain domains in just their current form, I don't believe that.
