Those days are long gone. I still remember ordering updates for MacOS (in floppy and then cd-rom form) and you wouldn’t see any minor or major fixes until the next big update. Today, a company like Apple has to update for vulnerabilities that could get them in trouble and if they’re going to do that, then why not fix a few other minor issues at the same time.
Would you really prefer to wait until a major update (done yearly) to get things like FaceID unlock with mask, or the current FaceID unlock with Watch? I know I’ll happily update anytime there is one available.
