GNU Make defaults to a single worker, and newer build tools (e.g. ninja) default to the number of physical CPUs.I wish there was an option for 'leave me a little bit of my machine to do stuff'.

Coming from JS or Python, imports in Rust feel weird. They're entirely optional aliases for fully qualified symbols, which are always available. I don't know of many other languages where you can just start using libraries. Java is the only one I can think of.

Assertions are a surprisingly nuanced design space. In a test, if I assert `x < y`, I really want to see the values of x and y when it fails. Do you define an API for every possible predicate (Python's assertLess, expect.js) or try to support the native syntax (c.f. pytest)?
