That’s not particularly unique, Mac OS and Windows have had compressed memory for years. No fiddling with setting needed either.
It's not just that it's compressed - the OS is also intelligently handling which memory should be on hardware vs. virtual. Effectively a lot of the memory concerns have been offloaded to the OS and the VM where one exists.

It's since become the default in several distributions, including Fedora.
