The nice thing about the Distributed Systems Annex is that it allows
to distribute existing applications that were developed without
distribution in mind.  With CORBA it's usually different: you have to
start by writing IDL for (at least) those objects that you want to
distribute, and in your Ada code, you have to adhere to a programming
style that is dictated by CORBA.  I would rather use Ada only, and not
care about distribution issues until very late in the development
process.

But you said "Ada=>IDL mapping"?  Do you mean there's a reverse
mapping that allows CORBA to be used for distributing existing Ada
applications?  That might be a different story.
