Dolby Atmos, at least, sounds good but it's pretty annoying because it's had the practical effect of making height channels proprietary in most systems. Springboard definitely isn't OK. There's no good reason that Airdrop shouldn't be in the Linux kernel and it probably would be if the protocol were well documented. You can use game overlays other than the Steam one, so there's nothing stopping Microsoft from creating an overlay that provides the Edge browser. Rich integrations are great but when the boundary is perceived by the user as being two different programs or systems, both sides of the integration should have well-documented public interfaces that support swapping out the other side (no "private API" funny business).
