I learned something new.
And ick, what a name. Why not --ignore-sparsity or something? Oh well...

Why this restriction? What if the user ran
git checkout-index -- '*.c'
That's not an explicit filename, but a glob.

So here I see you let it fall through to the code below that will
write the file to the working tree...but it doesn't clear the
SKIP_WORKTREE bit in the index when it does so, which I think is a
bug.

I added an 'exit 1' here, ran the test and then checked:
$ cd trash\ directory.t1092-sparse-checkout-compatibility/sparse-checkout/
$ git ls-files -t | grep folder1/
S folder1/0/0/0
S folder1/0/1
S folder1/a
So there's some more work to do on this patch.
