It's still common today. Everything the

Why write something portable when you can be "close to the metal"? :-/
To be fair, spectre-multdown-checker is a shell script, and while you
can use tput, that's not super-portable (some versions take termcap
names, some take terminfo names, and the only thing that has been
standardized is "init", "clear", and "reset"), and said
script was
designed to work on Linux and *BSD systems.
