granularly derived store

My use-case: I have an array of coordinates as input. For each coordinate I want to keep a set of offsets. The input can change, coordinates can get removed or added to the array. I contorted something together with mapArray https://playground.solidjs.com/anonymous/981e35fd-a794-479e-a8dd-777306b24a87 but I wonder if there isn't something a bit more elegant/primitive-y to do the same.

so the actual values of coordinates and offsets are totally independent, the index/order is the only synchronised? seems like this does the job: https://playground.solidjs.com/anonymous/0d62f7fb-5b80-4fad-a474-49e6bf232aad
