either move sounds like a good punishment for an isolated case of horrible spacing
I mean if people get uthrown->rested or they roll towards the stage and get fsmashed constanstly then this could happen just as easily.
Maybe you could even bait out something with WD back on a platform (i.e. the opposite of Falco being at center stage utilt'ing but this is a safer, sort of). Worst case scenario they don't jump at you so you can just jump or shield drop.
Shield drop uair is definitely not niche at all. You can consistently use it out of pressure, and if anyone is above or on a platform, you can always be more efficient with your movement by dropping below the plat (since you almost always want opponents above you as Puff) and simultaneously placing one of the most underrated hitboxes in the game above you. The only reason people don't spam the **** out of uair is because Puff's vertical acceleration (both upwards and downwards) is awful. Shield dropping allows you to throw out uairs instantly without having to position yourself with jumps. You can run across plats towards opponents and be uairing the next moment too fast for them to react to.
