I would prefer to keep the actual limit and check with a verify
that is below the protocol one.
The fact that previously the limit was 4 billions didn't means that
the arrays contained 4 billions elements.
About ABI is not an issue changing the internal ABI of a
library, basically most of the commits change it.
