The issue is that 'rdma' is a wrong term. It's not even used by qemu any more. Additionally iser runs on top of a variety of transport depending on what technology you have so encoding it as a transport is wrong.

IMO this is the only way to go. Specifically it will also make other things like disk type='volume' les weird IMO.
