This was the first time I'd heard of it, so I checked it out. In general, we support people creating whatever addons they want if they see something is lacking in the default sim. We're a small team so it's impossible for us to do everything everyone wants. :) For example, we created new German style autogen for X-Plane 11, but the fastest way to get more local variants will be probably via third party devs making add ons.
Reading through the .org thread, it seems like it is kind of complicated and requires a few additional downloads. So your mileage may vary.
