Less “intentional” and more “unavoidable”. There was limited runway to fix the S5L8900 design, the Cortex A8 wasn’t ready at tapeout, and so the ARM1176 was it.

If Broadcom hadn’t looked like they were fumbling the BCM2730 it would have been an ARM1132 instead, and history would have been a little different.

ARM1132? That is not a core I have ever heard of nor can find any reference to. I assume it would be some ARMv6 ARM11 though, a uarch that was already quite mature by the time the iphone rolled around.
