I may be mistaken but the difference of properties allowing "none" as value
to border-radius is that they all take keywords or functions as value while
border-radius currently only takes numeric values. So in my eyes allowing
it for border-radius doesn't bring any additional value. On the other hand
it doesn't harm to introduce it, either.
