As Fran├žois pointed out, there's a difference between a grid item
that's also a grid, and a subgrid.  You don't want to mix these two

The spec specifies that, right there in that section.  It looks for
the closest ancestor grid, or if it's positioned with named lines, the
closest ancestor grid with those lines.

Can you explain why you don't think you should be able to make
non-children part of a grid?

This doesn't work - we're not trying to name the rows/columns, we're
naming the lines between them.  All positioning is done by attaching
edges to lines (though you can ignore that if you just use 'grid-row'
and 'grid-column' to do the positioning.)  A single line can have
multiple names, as it represents different things to different
elements.  Further, if you rearrange your grid (such as with Media
Queries), what was previously two separate lines may become one line,
or vice versa.

I don't understand the suggestion.  The four positioning properties
apply to a single element, not multiple elements, so what would the
selectors select?
