Clap is a really fantastic command-line argument parser, especially using the "derive macro" they now include. Once you start dealing with git-like subcommands, and other complex cases, it Just Works. You get help, short and long options, defaults, repeated arguments, deserialization to custom types, etc. Essentially everything is accessible with a couple of lines of code.

Life's too short to build all of this each time. I'm perfectly happy to ship 2-5 MB zip archives, which is where a lot of my more complicated Rust tools wind up.

In this situation, if they were truly concerned about clap, I think they should have gone down to lexopt (https://docs.rs/lexopt/) rather than roll their own

If every odd utility is several megabytes, good luck fitting an OS in a meager eMMC.
