Is it a good idea to make this an exec-async?  There is really no state changes.
Printing it in the console-stream long with the
gdb version should be enough.

But if async is desired, how about a notify-async instead.

=mi-handshake,versions=[mi1,mi2,mi3],stable=[mi2]

As the doc is saying, notify-async contains supplementary information
that the client should handle.

Note: did not look at the patch.
