That was only one of the concerns; the other involves being able to set the MCD, but only when the Boss Bat is able to show, and only see warnings at "appropriate" times.
But between Bale and zarqon, the last result on what 'appropriate' was, became "use relay scripts to customize it" instead of "hardcode it" because different people have different opinions about what's best.
That's how I read it, too: there is no agreement on an implementation for this feature request that would satisfy everybody and hinder nobody - which is enough reason to reject it.
