This is a work-around for boards which have 'lcd' in their stdoutenvironment variable, but have moved to use driver model for video.In this case the console will no-longer work. While it is possibleto update the environment, the breakage may be confusing for users.This option will be removed around the end of 2016.
Removing this option at the end of 2016 is simply going to cause the exact same problem then. Is there any harm in simply not deprecating this feature? I suppose at least there's a warning that people should convert over, so perhaps they will and so the chances of people getting bitten by this well be less by then.
