Hello,
just curious, why would such a limit be useful ? The only thing I can think of is trying very hard to keep the headers very small (saving bits on size fields), but even for that a limit of around 4KB seems to be quite small - and besides, by now I think you have all seen how hard it is to avoid the alignment restrictions, which means aiming for a header smaller than 4B in your assignments does not make much sense (and possibly 8B would me more reasonable than 4B).
