I think you’re mistaking the stability of Apple’s x.0 releases as “negative effects” of security patches.
x.0 releases do a lot more than patching. Security updates are much smaller and more frequent than even x.x.1 updates

I wait a couple of days to make sure updates are not bricking devices. Waiting just a week saw 3 updates and a 4th within 10 days. Some of those updates saw serious crippling of capabilities of the device after the update.
