Your comment said:

Your comment makes it sound that the Rust team considers a four year old utility method as "newly added", and that's the reason why this method is marked as unstable. More likely, this "newly added" reason is something they add for any new unstable feature, and it is now out of date.
Considering that repository has 9,000 open issues, and 50,0000 total issues, you can imagine that this issue has simply not been prioritized. Rust being poor at prioritizing, handling issues, etc. is a totally separate discussion from "Rust thinks four year old code is new"
