The json/v2 prototype used to support a `format` tag option,
which has been removed for the initial release of json/v2 in Go 1.27.
The wrapper types in this package provide a way to avoid using
the `format` tag option for all existing use-cases.
The types are written to cooperate with other tag options
such as `string`, which may stringify JSON numbers.
We adjust cmd/vet/jsontags accordingly.
