I don't even know what these big flashy features are anymore. Every year I get asked by staff "Can I upgrade to <latest major Mac OS>" and every time I tell them they can, but they won't see anything different. There's not even big architectural changes under the hood to improve stability or performance.

Short of it being a requirement to use the latest version of Xcode (once they bump the minimum in the following Feburary), and security updates stopping, there's been very little reason to actually upgrade.
