I think thats sound advice.  If you use CLI for KDevelop (?) and then GDB
developers change the CLI output, it will break things for you and you'll have
wasted a lot of effort.

I don't think you'll get that.  GDB is a voluntary project.  You just have
to work with what's available (or pay someone).

I've learnt what I know about variable objects from using Insight, reading
the manual and looking at the source code.  I still don't understand the
asynchronous operation which only works under limited conditions.

If you are going to generalise the whole of MI and CLI from this one very
small example, then I can see that it would make you wonder why MI is more
stable that CLI

Yes, but you can easily parse the MI output and replace '{' with whatever
you want.
