This!

There's a recurring meme here and in other social media about rust being slow to compile, but anyone who's worked with Rust know that target dirs are a much more annoying papercut in practice than the relative speed of the compiler (which isn't appreciably worse than any other toolchain out there for the most common workflows).

It would help, yes. Here's one of my projects, that uses different subdirectories in target/ based on compiler options pre-commit runs:

    $ du -hcs target/
    190G    target/

Could you e plain the issue for a non-rustacean?
