Description
E.g., ncread(file, "w", (:, :, 1)) will fail, because it tries to instantiate an array that has 3 named dimensions but only 2 actual dimensions, as w[:, :, 1] is a Matrix.
@rafaqz by the way, I think Rasters.jl has this subselection feature implemented already right? Because it first makes an "image" of the full dimensional array without actually loading numeric data, and then you could subselect this image.

Research direction
Start by reproducing the ncread(file, "w", (:, :, 1)) example and inspect the ncread subselection path. Compare its handling with the image-based subselection approach mentioned for Rasters.jl; done means integer-indexed subselection succeeds without a dimension mismatch.
