Feature Request: Alternative to isLoading for useSWRInfinite

[VladimirMikulic]

Description / Observed Behavior

isLoading only applies to the initial / first request.
I have a project with many infinite scrolls and this is the line which is repeated (taken from your infinite loading example):

const isLoadingMore =
    isLoadingInitialData ||
    (size > 0 && data && typeof data[size - 1] === "undefined");

isLoadingMore in this case is true while the next page data is being loaded and false otherwise:

• Request to /page/
• isLoadingMore = true
• Request to /page/ done
• isLoadingMore = false

I was wondering if it would be possible to expose a property like isLoadingMore for useSWRInfinite so we avoid repeating this block for every infinite scroll in the app. Or maybe make isLoading to be true for all loading useSWRInfinite requests? (i.e. regardless of whether it's initial request or subsequent)
