A few targets don't emit RTC_CHANGE, we could restrict the event to
the tagets that do emit it.
Note: There is a lot more of events & commands that we could restrict
to capable targets, with the cost of some additional complexity, but
the benefit of added correctness and better introspection.
Note2: The rate limite could perhaps be part of the schema, and the
common event emitter code, to simplify the need of custom and #ifdef
code in the monitor.
