This strikes me as one of these artificial limits that gains us almost nothing (what if the platform supports less than 32 or it supports 32?), and creates these backward incompatible YANG issues (ranges that have to change) that are part of what is driving the complexity in the YANG versioning stuff. Why don't we just have a no range u16 or a 1..max range?
Thanks,
Chris.
