Looking at the Unix to Plan 9 translation [1] gives me a different opinion. To name one egregious example, omitting find(1) in favor of piping du(1) (what is supposed to be a disk usage analyzer) to grep(1) is not an improvement; it's just user-unfriendliness in service of minimalist aesthetics. (Contrary to popular belief, find(1) is not a particularly "bloated" program; Rust's "fd" implementation is under 7,000 lines of code [2], about a third of the size of Lua.)
