Steps to reproduce:

A bug for this draft allows to extend the possibility of CSS Variables

It's like the duo of SASS rules: @mixin/@include
Component: Untriaged → CSS Parsing and Computation
OS: Unspecified → All
Product: Firefox → Core
Hardware: Unspecified → All
I think we'd at least want the spec to be taken up by the working group.  (Or did the WG already agree to that and it just hasn't moved?)
The only CSS minutes I found on the topic are:
which were summarized as:
>@apply rule
>  - TabAtkins brought his proposal for an @apply rule to the group,
>      available here:
>  - The overall reception was positive, but there were concerns
>      about the feasibility of certain behaviors due to how style
>      resolution works.
>      TabAtkins will work on solving those problems before he brings
>      the proposal back to the group.
Summary: Support of CSS @apply Rule → Support CSS @apply rule (using CSS variables as mixins)
Fwiw, it appears TabAtkins changed his mind since then though:
Severity: normal → enhancement
Priority: -- → P5

Well, the spec is now abandoned, so this feels like a WONTFIX to me.
