Isao Moro is not the original series director so it's not the end of the world. In fact, if I have to be honest I think with him directing City Folk I don't think his merits are too impressive. New Leaf had Aya as co-director and it was better imo. The city in CITY Folk was just a bastardization of Animal Crossing's unique design; by putting a lot of the random elements into a hardlocked space you could visit at any time, not to mention that the city is completely static without the joyous systems that the town offers, so it felt inorganic and artificial visiting it every time. New Leaf understood that and rightfully cut the scope of the city portion down and added a better more "hygge" flavor to it.
And even Aya isn't end all be all. The original director will always be the one who best understands the core of the franchise and they're proven twice that they can mostly retain it entirely without him, due to Aya and Moro taking the reins in the more recent iterations.
Even if it was Pocket Camp's director AC Switch could still be a charming and eventful game with good vibes, even if it would likely end up feeling like it was built for grinding. I don't know exactly how much of Pocket Camp is designed as it is due to corporate mandate on mobile development, but going by other spinoffs like Happy Home Designer I do worry that there are staff at the helm of the franchise who, similarly to Capcom and Resident Evil, just don't see Animal Crossing for anything but it's aesthetic, but it is important to me that whoever makes them understands that the game isn't about instant gratification or outright grinding, but being in the moment and slowly growing over time with no rush.
