100% this. Sleep on Linux is perfect in my older XPS (after I manually enable it). Lots of reports of it not working on newer laptops.
While I agree it doesn’t have to be a walled garden, you do have to admit that apple wouldn’t ship a laptop that couldn’t sleep properly. They are so much better at real world design than other manufacturers who were happy to abandon s3 in favour of making laptops into phones as if anyone actually wanted that.
