Apologies. I went to school during the switch from DSM-IV and DSM-5, so the first half of my classes involved IV and the Axis system, while the latter half involved the DSM-5. I keep wanting to use aspects of both systems- both have their uses. For example, the Axis system clarifies a major difference between the disorders classified as I and II, while 5 did some wiser choices regarding cutting certain redundancies in regard to some general clinical disorders and the trait system sounds interesting.
Springy claimed to have the acronym for Dependent Personality Disorder in that screenshot of her "diagnoses," which is why I mentioned DPD. I also have a copy of the DSM-5. HPD is still listed separately from BPD and DPD is still a listing in it. It notes in the introduction to the PD section, "As this field evolves, it is hoped that both versions [of the personality disorder diagnosis] will serve clinical practice and research initiatives respectively." A later overview of the changes between IV and 5 also suggest that both models are to be used together.
I also don't know about the use of that in diagnosis compared to the traditional idea of PDs, but that's statistical information we may not get for another few years. Or, at least, not something that's both accurate and a large enough sample to generalize until then. People may either still be stuck on the IV criteria and system right now because they need to adapt or they may overuse the trait system when the traditional method is more appropriate due to the novelty.
As for the diagnosis of Springy, I'd rather not touch the question of what she may actually have because I'm still working my way through all 200 pages of this thread. (It's just clearly bullshit that she has half the traditional personality disorders and a shitload of other stuff.)
