That is, with added "type" field? No objections from me.

I'm not sure about this. If your really want to send several command, there 
are two mechanisms:

1. You can use the "token" in original MI command, which will be returne in 
reply.

2. You can just send the commands anyway, and keep a list of commands for 
which there's no reply. I believe that the order of replies and commands is 
the same, so it's easy to match replies with commands.

Anyway, extra "type" field won't hurt much.
