I hate how misunderstood osdd-1a is. I made a post a while ago talking about systemhood with a lack of amnesia barriers like osdd-1b and alters like osdd-1a, and so many ppl were like "so you mean a singlet" no that's actually not what I fucking said. Osdd-1a does not mean "doesnt have alters" it means theyre less elaborated or differentiated, like theyre all fragments or just different "versions" of the same identity, or maybe they all appear the same in headspace but use different labels and names. The best analogy I have for it is all those 2016 sans undertale AU ensembles and comics people would draw, theyre all the same person just different "versions". It doesn't matter if alters aren't that different from one another, if you still hear them in ur head and they still front then they are not just "mood states" like bpd or cptsd.
Osdd-1a systems are still SYSTEMS. They're still PLURAL. If they didn't have alters but still had amnesia barriers then thats not what a fucking system is, that would be diagnosed as dissociative amnesia (which yes, is a separate dx despite being a symptom of osddid!)
Sorry for the rant
