Wait, what? Ubuntu server and macOS both have awk preinstalled (which is true for any POSIX) and gawk not preinstalled. Those are what I (and many other developers) spend 95% of my time on. And I do use awk frequently.
Edit: Okay, /usr/bin/awk is actually gawk on Ubuntu, so I was wrong about that. Still, macOS isn't very rare.
How many OS X users do you think are actively using awk in any of its variants? What percentage of total awk usage is on OS X, do you think? OS X may not be rare, but it seems highly unlikely that many OS X systems see frequent usage of awk.
To be fair, /usr/bin/awk was mawk for a long time with Ubuntu. I remember getting in a heated discussion with GAWK’s maintainer that he should allow a way for [A-Z] to never match lower case letters (it does in some locales) so that we didn’t have to use stuff like [[:upper:]] and [[:lower:]], which do not work in mawk.
The claim under discussion in this deep subthread is "it is very rare that you see a system that awk is frequently used on that doesn't have GNU awk installed", so this is irrelevant.
