Most Rust releases are almost empty. The ones that add something like async are exceedingly rare. Maybe once in a few years? And what would be the point of sitting on small, well tested, changes for six months or a year? What if it's two or three years before the next major feature is ready for stable? Do we have to hold back all the small improvements too? For example, making a function const allows it to be used in more places. This can be a big benefit for users. It doesn't help anyone to delay that once it has been decided it is const.
