IDL complilers have nothing to do with managing objects... Or at least
MiG doesn't. (Don't actually know any others.)

The purpose of the IDL compiler is simply automating creation of code
for handling data structures sent in an IPC (marshalling), and
dispatching different types of requests on the server side. It does so
by generating code from a simple interface definition. It doesn't define
any resources, create any objects, or anything like that.

I wonder, have you ever looked at what MiG actually does?...
