OK yeah the first time I saw pluralkit and someone said it was for systems my first thought was "there is no way that there are enough people with DID for this to need to be a common plugin?" I know that fandom and online spaces tend to have a heavier presence of people in marginalized communities but it felt weird?

That said, the National Library of Medicine quotes a stat that DID is diagnosed in 1.5% of the global population, which in a world population of 7 billion about 100 million people, so maybe I'm mistaken. https://www.ncbi.nlm.nih.gov/books/NBK568768/ link to stats if anyone's curious.
