PS4:
Why is this upper limit hardcoded to such low value? Can't you also allow bigger MTU if you want to? […]
on public networks the GSMA GRX documentation would mandate you to be in the usual low-MTU range. But for example in a private cellular network, you might indeed operate your physical ethernet with jumbo frames (MTU=9000). I'm not sure if any UE would accept such large MTU during PCO, or have ever been tested with it.
Fundamentally I agree with lynxis' comment, if there's no good reason we shouldn't introduce arbitrary constraints.
