Just today I came across a modded HSiFS demo that changed the stages for those of LoLK; they look like they are 1:1, so I checked with stage 2. If you stay in the bottom center, only Reimu can time out the big fairies before midboss Ringo without shooting, and in this modded HSiFS... she can't. She dies at the same time every other character does there (or in LoLK, for that matter), and I let myself get hit before the fairies appeared to be sure I was on center, so it seems like it's gone.
Marisa still has her lower PoC, at least. As for Cirno and Aya, I haven't played much of either to notice anything so I don't know, but I wouldn't think it weird if their abilities were just "her shot is very wide" and "she moves very fast"
