While there is a some naming activity over what to call such constants, i think the use a ‘_’ as the first character of a public API artefact should be strongly discouraged, such usages are more commonly associated with internal artefacts or generated code and using such a style for public artefacts sets a “bad" precedence IMO (first use in the Java APIs AFAICT). There needs to be a really strong justification for such public use and at the moment i don’t see one here.
