"#Rust development is going too fast (because they are stabilizing features I don't care about) and going too slow (because they are not stabilizing features I care about!"
There are only so many #RustLang contributors, hours in a day, days in a year to get to everything now, and some features are reliant on other, less flashy work that needs to happen before they can be even attempted.
But people are putting in a lot of work, the codebase changes so quickly that it is hard to keep up.
