If you only mandate the use of [$i] as a way to lock down the entire
file, it will be equivalent to a group section named "$i" which is
pretty compatible with the current FDO desktop file spec.

Note that Gnome isn't complying very strictly with the FDO desktop file
spec anyway, so I wouldn't worry too much about that aspect.
