It might be useful to provide a method for retrieving pixel values of the displayed HiPS layer for the current view at a given zoom level.
One usecase, particularly valuable for FITS HiPS maps of physical parameters, is generating histograms to assist with dynamic image cuts. This could be easily implemented if healpix values were accessible in the layer objects.
