Iirc in a prior discussion we had decided to drop the limit altogether
(and in fact all the MAX_* values living there), as there was nothing
found actually requiring there to be a limit. This probably was in the
context of some (perhaps draft / RFC) patch, so I'd guess whoever
it was then lost interest and didn't send a full patch as agreed upon
during that discussion.
