Yes, I thought the same initially. But then what about other existing MI
consumers?

From what I understood from Jonah's comments earlier, this would break (at least)
CDT. So CDT would either have to stick with MI2 (not great in a long term)
or refactor their code (not sure CDT guys would be happy to do so, especially as
- I presume - CDT needs to support wide range of GDB versions already in the wild,
a problem I do not have).

While I personally agree with you and will be happy to go that far, it'd break
existing consumers - something that should IMO be carefully discussed and planned.

Adding a new option as I proposed as an alternative will be backward compatible,
indeed at the cost of more convoluted code in GDB itself.

Is anyone from Emacs community around? Or any other MI consumers?
