Hi Kevin,
I restart every once in a while or when required for some update, be it Mac OS or something else. There's also times when I travel for work and this thing gets shut down, not to mention the occasional power flicker or failure that will cause it to shut down. The only time I've had to re-run the command, thus far, has been when a Mac OS update was applied, most recently when 13.4 was released, major Mac OS releases are not automatically installed. I haven't had it come back on seemingly at random like others have stated.
I hope whatever is going on with these settings or whatever the problem may be is resolved soon if Apple even has it on their roadmap. Sorry I'm not more active on here for replies and whatnot. I need to setup notifications...
EDIT:
Also, I ran the uptime command and it was only up for 8 days. Whenever 13.4 was installed was when I ran the command again after it was finished updating and the spin down issue came back, since then its been fine.
