This is my policy for most of my software unless there's some kind of critical exploit. Software updates have been the cause of many breakages for me, but I have not (yet) been affected by running out-of-date software (to my knowledge).
I am considering switching back after seeing how terrible Firefox is. For example, it has a memory leak that causes a crash after 3-4 days of uptime.
Excuse me, Mozilla? Firefox should not be collecting 20-30 gigabytes of committed memory in the first place. They must be high or something.
FWIW, I would still be using macOS... if I had any choice.
