Telling the plugin about an update rate makes sense (though this is not
necessarily directly related to the actual UI update rate, since there
can be all kinds of mechanism in-between, e.g. network)

We could simply define a property for that and pass it as an option.
Easy.  Changing while an instance is running seems overthought, though
one could use the dynamic option interface to do so if really necessary.
