Isn't it better to have the CLI-style output be followed by the
MI-style output, with some clear separator between them?  The front
end could then filter the CLI output to the display, while keeping
the MI output for itself, to sync itself with the debugger.

Nevertheless, the CLI support is required, I think, because the user
of the GUI should be able to type CLI commands directly.  The GUI
front end will never be as flexible as GDB command and scripting
language, even if all the commands are supported in the MI.
