Do you restore to factory settings every time you update or do you use a backup that was created on a jailbroken device?I won't go into details but just because you didn't have problems it doesn't mean others won't.
What you're posting and suggesting goes against many jb dev groups that know about code and the jb process.
So do whatever you want but try not to suggest to others cause you can pursue them to do it the opposite and wrong way trusting you that you know better.
Like I said, worst case you could restore if it caused any problems, but I know a lot of people who do it this way and don't have problems. It's not just my own experience.
