Sorry for the delay. I am not sure if there is any interest from developers. The spec was updated last April [1]. I started this from the spec change and the related crbug.
I filed an issue[2] last week and got a comment[3] in WebKit. The reviewer's worry would be that the lifetime of these objects is not carefully defined and as such when they return null and non-null can end up varying in edge cases. I thought this was very clear to be changed in spec that CSSOM was not matched with at-rule behavior and it has low compat risk.
