I think it's fine if you're on a dev team that decides to include these tools in its shared toolkit, but none of these rise to the level that I think warrants them being a dependency for a broadly-distributed shell script. There are slightly-less-terse alternatives for most of the functionality that only rely on core utilities. I don't think it's being a good citizen to say "go install moreutils and its dozen components because I wanted to use sponge instead of >output.txt".
