The author mentions Sway and i3 window managers as examples of finished software. I'd be interest if anyone has more examples. What is a piece of software that is feature complete in your opinion?

A couple more examples I can think of:

- jq: https://stedolan.github.io/jq/

- pass: https://www.passwordstore.org/

- tokyo/kyoto cabinet: embedded key value database

- awk: text processing tool / programming language

- (almost per-se) any game that shipped on physical media
