We try to support the newer things that are generalizations of the older things. One example of this doing all your list styling with a user agent stylesheet using generated content, instead of hardcoding how list bullets and things work. Also, in some sense, we are doing what you want simply because we don't have a lot of features yet and we prioritize things that are important and things which would have some affect on parallelism or architecture.
