A lot of the "features" - most of them even - being added to Rust nowadays are just filling holes in the language. Things you might easily assume you could do that for arbitrary implementation reasons, you cannot. A lot of them are basically "fixing and improving the language" IMO. In addition, frequent releases do a better job of incentivizing taking the time to get the design right, because the consequence of missing a release window is that it gets delayed a few weeks, or maybe a few months, instead of a few years. You can totally see this happen with C++ for example.
