Given that 'common practice' is being documented and no servers (that
I know of) have a DEBUG command, or return x9x status codes then I
fail to see the problem with dropping the x9x code documentation.

Even if a server did output x9x codes - surely they are for LOCAL use
and should not be enabled in a deployed server.
