Is there an reference that could be listed to either
1) A upstream mailinglist/patchwork link that proposes adding this patch
2) If the patch below can't be upstreamed, a reference to the commit
that is reverting this support you're adding back in and maybe a
summary of why the backwards compatibility isn't' accepted.
