In-order execution does not mean that there is no branch prediction, it just means that the number of instructions speculated is much smaller.

Yes, it would be quite strange not to add it at all, especially since it was available since Pentium days.

No, it is not comparable with a 'proper' CPUs because it was still gutted hard.

IMMSMV all that stuff consumes a lot of die space, so it makes sense to throw it out if the performance is enough.
