We need less frequent but more substantial updates.
Wait... you seriously want Apple to hold off making security updates? Because part of this update included security fixes.

I’m saying their constant updates bring the need for constant security fixes. Even the most dire hard Apple fanboy knows they launch crap half baked. It’s a vicious circle. I want to see major iOS releases every two years, I’d be ok with every 3 years. It would help drive iPhone sales as well.
Software is incredibly complex. Even if they took 5 years between updates I’d wager there would still be security vulnerabilities discovered.

For example, DDR3 RAM launched in 2007, about 4 years after DDR2. In 2014 the row hammer vulnerability was discovered in DDR3. It took about 7 years to find the flaw, and the row hammer flaw still affects some DDR4 modules despite now taking it into consideration. That being said, it’s safe to say no amount of years between updates will guarantee the lack of security vulnerabilities.

Always weighing the urge to update immediately, or waiting until I'm confident that it won't brick anything.

Feels like we have to update these things every other week…

We should be applauding Apple for providing a timely security fix before it can be exploited.

Bug fixes related to "half baked" software releases typically aren't security updates. We'd likely still need the same number of security fixes.

I'd like to see more stable software releases - I agree with that part of your sentiment.
