Logically yes, but anyone who’s been doing it for more than a couple years has been burned by an update at least once and won’t easily make that mistake again.
The mistake here is not the apple update but lack of backups.
The mistake here is that assuming things will forever remain the same and thus you don’t need to update your software, when security enhancements require it.
Even if you properly backup everything and can downgrade after an update, you’re still burned by an update if it breaks your software. Which is why most musicians will be at least a major OS version behind, giving vendors the time to update.
