Honestly would never see something like this writeup from MSFS add-on developers. They are a protective bunch who share nothing with each other. This is in contrast to X-Plane add-on developers, who are friendly and collaborative.
I guess it also has to do with whether or not someone will go "oh cool, cool, okay I copied everything you did and quickly released a shittier version that made me a few bucks but turned the flightsim community off of the plane you're still working on" =(
I think a lot of it has to do with how MS has dealt with add-on developers in the past. After FSX was abandoned by MS, if you wanted new functionality in the sim you had to build it yourself. So add-on developers would all have their own propriety tech for things like Avionics, nav and the flight-model.
Today MSFS is constantly updated with new functionality, so you can just focus on your project, but old attitudes remain.
