Review Comment:
Suggestion: create a constant with `new ElasticSemVer(1, 5, 0)`: avoids
creating a new instance every time this logic is executed and improves
readability because the name of the constant can document the meaning of this
particular version (maybe `MAXIMUM_NULL_CHECK_VERSION`?)

Review Comment:
Just a side comment, not related to this PR. All the other datastructures
used for the fields in this class have a well-defined iteration order, except
this one. Could this be an issue? If so, for consistency with the other fields,
we could use a `LinkedHashMap` here. Or if the order is not important, then we
can use `HashSet` for the others instead of `LinkedHashSet`.
