Let me play devil's advocate for a second, because I feel it’s more nuanced.

Pros:

- [for users] 15.8.5 patches one high-profile bug.

- [for Apple] minimal effort which translates to longer perceived support time

Cons:

- It leaves unpatched multiple bugs fixed in iOS 16-26, and so it might give users false sense of security

I'm on a fence here, especially without real numbers
