I see you haven't understood what I said. The specific examples I cited were real in the past. Even if those, specifically, are now solved, am I to believe this will never be an issue again? Because I think what's more likely is that non-Windows emulators will be behind by a few years in the future as well.

They're not behind, I doubt they've ever been behind, and if they get behind, it's a trivial matter to prod the package maintainer for an update. These emulators support Linux as a first class platform and hell, for several of them Windows is probably a second-class platform.
