Why do you think it's disallowed? The base grammar of each query is
just the "expr" term from the Core Grammar, which definitely allows
calc() (since it's what's used for all the declarations).
If browsers don't implement, file bugs. For efficiency, I think
calc() is usually handled specially in implementations, and so has to
be manually made to work in new places.
