I'm not sure I fully understand the gripe you have here. Rust releases a new compiler every 6 weeks. Many releases just improve optimization and a handful of newly stabilized APIs, or existing APIs newly made `const`, or whatever. When a big feature is finished, it is put out in the next release. There is no sense in which this increases the pace at which these new features are developed or released; if Rust released a new version yearly, we'd simply see extremely large releases some years (including, say, the new async/await system) and relatively small releases in others. What it does mean is that backwards-compatible refinements and bugfixes can be quickly and easily added to the language, which I think is a good thing. I'd be interested to know what you'd prefer, though!
