grid-cell-stacking doesn't make any sense applied to the grid items;
what would you do if two grid-items put in the same grid cell
specified different values?  So, yes, it should be specified on the
cell.

As the note in the spec says, though, the 'rows' and 'columns' values
should instead just be done by setting the 'display' on the grid-cell
to 'flexbox'.  The 'layers' property should presumably be done the
same way, with a display value that works in the desired fashion.
This would probably involve inventing a relatively simple new layout
model like "Stack Layout" or something.
