Indeed, and I've found the same myself - my comment was about the reliability of the OS sleep functionality, and deliberately says nothing about the wisdom of never rebooting! I have actually found both Windows and macOS generally pretty good if you leave them running for weeks at a time, but it's one of those things that's best done only if you really need it (and can accept a non-zero chance of something going wrong). They're not so very good that I'd actually recommend doing it routinely. A reboot every 1 or 2 weeks massively reduces the chance of weird stuff happening.
