Introducing a limit has the potential of breaking some configurations if
they have large zones.

Given that this vulnerability only affects slave NSDs, and that most
configs will have well-known masters, I don't think it's such huge problem.

FYI, Knot DNS has also introduced a similar option, but it also defaults
to unlimited.
