@matt I just don't think it's necessary. And I say that from how I use both Macs and iPads. I get the curiosity and the strong desire from what I consider a small sliver of the market, but for the way I see folks I support (a lot of family and friends) who love their iPads, adding too much potential complexity would not be welcome.
That said, for those who want better audio support on iPad and clipboard mgmt, those area that make sense and should require a full macOS to implement.
