you've hit on why apple is spending all its time developing the ipad into a laptop replacement (despite relatively flat sales) rather than really improving macs/macOS. they keep saying they're not trying to do this, but it's been plain as day for a few years now (with the ipad pro). there's no precedent for ipads to "upgrade" to another OS/firmware, unlike macs, so customers can't claim anything was taken away from them. plus, macs are considered essential for developing for iphones/ipads, so apple doesn't want to disenfranchise ecosystem developers too much by locking down macs, especially when laptops are a dwindling segment anyway.
