[mkgmap-dev] Did anyone realize cGPSmapper speaks Garmin NT?

Hi list

I remember many discussions and comments about how mkgmap produces 
Garmin's legacy format only and the NT format is still a mystery. Today, 
I was pointed at a discussion of the Polish UMP project (similar to OSM, 
strongly concentrated on Poland and surrounds). As I happen to be Polish 
and thus read the language, I browsed their wiki. I noticed that they 
are producing Garmin NT maps. And then I found that their tool chain is 
based on cGPSmapper [1]. So, is the Garmin NT format considered reverse 
engineered now that the cGPSmapper source is open? Or has this 
interesting fact been missed somehow (I certainly was unaware of it 
until today)?
