"@version" will give me absoluely nothing, it has no defined semantics.
I say'd only that I sympathize with the idea, not with the proposed
semantics. It's not possible to have the proposed mechanismn, support
for a CSS Version is mutually exclusive, if a user agent supports CSS
Level 3, it cannot support CSS Level 1 or 2 and likewise (according to
the latest drafts).
