Your FixedPoint approach is equivalent to pts //. {} :> Nothing, i.e., using ReplaceRepeated

I am not familiar with skeletonizing. However, as I see your desired form of the result, maybe a good idea would be to first apply Flatten to the list and then the operation that I proposed.

It almost achieves my aim! But as mentioned in my post, pts is a really long list, which even include a skeletonizing OutputSizeLimitSkeleton[100], for example. This makes your method not work for those skeletonized sub-lists. Is there any way to make it take effect into the ignored elements, instead of must clicking show more below the long list to expand it before applying FixedPoint. Thank you very much!

Please note there are 4 layers of {} before reaching the non-empty elements in my example. Your answer actually give the same result as DeleteCases[pts, {}, 3] for my example.
