The use case is allowing other text decorations in the future[1]. If the
order should be different depending on the line decoration, I'll put that
into my proposal, which I'll publish the next days.
As I understand the CSS 2.1 specification fantasai mentioned[2] it's just
describing how line decorations of different elements are painted in regard
to each other, but it's not described how they should be drawn in relation
to the text.
