You can find more by searching for `isBlank` on Wikidata project pages (most results use `!isBlank` to filter out blank nodes, but there are some non-negated uses too). Thanks for the links, I was not aware of these usecases. As to what I meant when saying that these triples are not interesting, I did not think that they could be used as filters like that, what I understand about blank nodes is that they are useful to link triples using a resource that cannot be named. In this case they do not link anything and we seem to just use the fact that they are "blank" to determine/filter something. Perhaps an approach similar to wdno would have worked here? Anyways, this is certainly not worthwhile reconsidering this at this point and I'm certainly lacking a lot of context as to why such decisions were made. Also I realize that this ticket is lacking some context, I will amend it to mention the reasons why are investigating bnodes.
