You're right, and I wasn't talking about getting the instruction coverage right - most software will have some idiosyncracies that will need to be discovered and worked around. Apple, as big as they are, will still need to discover some of these things in prod post release, I would be surprised if they didn't. I'm sure Spotify and Safari and the like will work on launch day, but I'm not too sure about Postico, Disk Inventory X and others. All of this would be fine if I trusted Apple to care about developers and niche users, but I just don't see it.
