Eh, I don't see much difference between older MacOS versions such as Mountain Lion compared to Big Sur. Similarly, I don't see much difference between Ubuntu desktop distros in terms of differences across versions , say from 16 to 20. Therefore... I don't see a being "one step behind" as any kind of issue. I've never run into an issue with past versions (such as those menntioned above) of OSes not running what I need them to run. Personally, I'd like to see a Linux version which is very close to Apple so I can use it (such as OP's), instead of expensive Apple computers.
