I agree with both of these changes.

I agree that this is an improvement, but still have some misgivings about
how clear it will be to authors. I've replied in that thread.

I think this would be OK, but it's a bit trickier than Flexbox.
Grid-placed, non-overlapping grid items don't really respond to changes in
this property. So I can see some confusion arising when someone sets order
on all of their grid items and sees either no effect or only a partial

Would the auto-placement algorithm take order into account in any way? Say
I have three grid items in a 3x3 grid, and each is small enough to fit in
any grid cell. I give them order values of 1, 2 and 3. These would
auto-place in the top three cells of the grid. Now I take the 'order:2'
grid item and place it in the center cell. I might expect the 'order:3' to
land in the middle-right grid cell. As I understand the current algorithm
it would actually place the 'order:3' item in the top-middle cell, which
isn't exactly "ordered" in the way that's been specified.

Either set of terms would be OK with me.
