Hi!
OK, I did not think it might confuse users, the label needs to be changed.
Yes, I think it should made clear that it should not be used for actual values.
It's of course not intended to use in statements which have no value, it's just an attempt to express wikibase data model in Wikidata. https://www.wikidata.org/wiki/Q16354757 is not Wikibase Data model :)
Which reminds me of https://www.wikidata.org/wiki/Q1061035 ...
