yea, this was just an idea because Marcel said:

"... you might want to push that device into a special mode to allow
programming of these settings"

and that's for me the dfu mode. My idea was just make the "new
operation" accessable in dfu endpoint only.

Nevertheless I am also fine with normal application operation, or making
some special bus access cycles to get into "privileged mode" or
something else, everything is possible.
