Like others in this thread, I would caution *against* overloading P31 "instance of" if possible.
When a somewhat similar issue came up, re how to artists that were of interest the the "Black Lunch Table" project https://www.wikidata.org/wiki/Q28781198 that works on coverage of visual artists of the African diaspora, the solution adopted (after quite a vigorous debate at Project Chat) was to use property P972 "catalog" with the value Q28781198 to mark artists that were of interest to the project.
A similar approach could be used here, if a project has a list of works of interest, that it would be valuable to record inclusion in.
Best regards,
James.

Implicit heterogeneous unordered containers where members sees a homogeneous parent. The member properties should be transitive to avoid the maintenance burden, like a "tracking property", and also to make the parent item manageable.
I can't see anything that needs any kind of special structure at the entity level. Not even sure whether we need a new container for this, claims are already unordered containers.

I'd like to propose a fairly simple solution and hear your feedback on whether it makes sense to implement it as is or with some modifications.
create a Wikidata class called "Wikidata item collection" [Q-X]
This sounds like Wikimedia categories, as used on Wikipedia and Wikimedia Commons.
