Yes, that´s true - weather is also good point. Here is an official statement from HiFi Tech (Active Sky) for a possible MSFS implementation of their weather engine:
"MSFS: We have received tremendous support and encouragement from the community to create an Active Sky for MSFS weather engine and we really appreciate all the feedback! While Asobo and MS have done an incredible job with the new weather system, it has clearly stoked the demand and need for Active Sky features for more advanced weather experiences. We’re looking at this as a future potential platform to develop on, but currently, we are not aware of any weather extensibility and we are not sure at this time what the timeline is or what the eventual possibilities will be. We have prepared foundational components for an eventual MSFS Active Sky weather engine, and as soon as we have the capability to interface with MSFS, we certainly will. We are anxiously awaiting more news and updates to the MSFS roadmap along with planned SDK improvements and will provide further updates when we can.
Anyone who would like to see MSFS weather-related SDK functions and potential weather add-ons from any developer, sooner rather than later, should upvote this wishlist item posted on the flight simulator forums: https://forums.flightsimulator.com/t/open-up-the-weather-system-to-3rd-party-devs."
