However, taking "Command-line Applications"¹ as an example it lists six alternatives. I think in the version I'd like to see a good few of them would disappear. For example, I'll presume plac/fire/cement aren't in common use given that only two are packaged in Debian and the two that are don't have reverse dependencies. Cliff looks largely uninteresting too, as outside of OpenStack nothing seems to use it.
I think my ideal implementation would probe recent releases of popular packages for dependencies to see what the community has settled on or moved to. I also suspect this comment that somewhat moves the goalposts also points to the difficulties of maintaining such a document.
