As to your first question, The answer is probably yes they can simply because until they say so, you are still on the registry. You would of thought the Pa Supreme Court would of given PSP guidance on this. Something like, “Hey, you have “x” days after the decision is final to get your stuff together. If you can’t do that, then we will remove EVERYONE.” That would of got their butts hoping. Otherwise, they can just take their time, let the clock run out, and then say “Oh I am so sorry. Muniz said you were to be removed NOW, however this new law says your are screwed. Better luck next time!!!
If the state can just “ignore” a Court ruling, why even challenge the law in the first place if they can just work their way around it? Also their was a post on here that said due to vested legal rights, the state can’t wordsmith their way out of a court ruling. However, with 1952 that is exactly what they are doing? Whoever made the “civil law” exception to ex post facto was dumb, because that is what the state will claim every time.
