It looks like Apple put their own people on this one.
If they want to maintain this, the Godot foundation needs to be extremely clear about that. You're talking about an extremely niche platform that will require tons of ongoing maintenance.
I would have hoped Apple also spent time working on the general engine and maybe tackling some bugs. Maybe they did maybe they didn't.
Even debating support for a niche platform is a distraction. Noise.
And since Apple is here, please help adding support for Apple TV. Apple and Android TV support sometimes makes the difference when choosing an engine.
