Regarding enhancements to ns/import/etc.: Not to speak for Rich, but he has in the past been resistant to modifications to these elements to support CLR vs JVM. Regarding Int32 vs Integer: They are really not equivalent. Int32 is equivalent to Integer/TYPE or a ^int type hint, not to java.lang.Integer. There is no CLR equivalent to the JVM Integer, Long, Number, etc., a fact which is currently cause me no end of problems as I try to incorporate into ClojureCLR all the compiler work RIch &co have done for 1.3. In fact, with 1.3, you will not be able to provide Int32 type hints on fn args or return values. CLojureJVM in 1.3 disallows primitive type hints in these places, wiping out ^int (JVM) and ^Int32 (CLR).
