How to implement GDB MI command in Python?

Hi

I'm using Python to extend GDB by new commands. This works fine. Now I'd 
like to call these commands from within Eclipse/CDT. Because GDB 
supports CLI command in MI-mode, I can call my Python functions by CLI. 
BUT It would be better, IMHO, to use MI commands, especially for 
GDB/Python commands that return status information and errors.

According to my research, it's not possible to create MI commands by 
Python. My questions:
  - Is this correct?
  - If it's correct: Why is that the case? Has it simply not been 
implemented or are there technical issues/limitations?

Thanks
