“2) iOS apps on OS X. Why? Does anybody want this? The way I see it, web apps are perfectly adequate for the desktop environment when it comes to stuff like checking my bank account or browsing Hacker News. I don't want to deal with a desktop app to do any of the stuff I can currently do via a browser. Is there actually a use case?”

Right now many new desktop apps are just badly ported web apps wrapped in electron. They are slow and eat a lot of memory as all of their UI is a being rendered in a glorified standalone chrome tab.

This is less about iOS apps on OSX and more about making it easier for the iOS developer ecosystem to build desktop apps. Right now it’s web teams that are building desktop apps because for most companies it’s too expensive to hire a dedicated desktop team. Even big apps like slack/WhatsApp use electron.

Making it easier for iOS developers to build desktop applications with the APIs they currently use should hopefully lead to higher quality apps.
