@tabatkins I am late but thank you.
Could you also clarify whether the requirement below should apply to `var()` regardless of back-compat?
> Functional notations are serialized without {} wrappers whenever possible.
I.e. should `var(--custom, {foo, bar})` serialize to `var(--custom, foo, bar)`, while `var(--custom, {{} foo})` should serialize as specified?
The {} block is said to *represent* its contents, and I do not see it being extracted in [substitute arbitrary functions](https://drafts.csswg.org/css-values-5/#substitute-arbitrary-substitution-function), so I guess it is no longer present after parsing.
