At this point, the core team feels that we have not fully explored the design space here, and that known alternatives (e.g., making the UTF-16 and UTF-32 views of a String mutable collections) might provide a better long-term solution. Moreover, the String type itself is undergoing a significant re-evaluation, so the core team feels that improvements to String should be delayed until the newer design is better understood.
