It's poorly maintained. Large parts haven't been updated in a decade.

Take a basic command, `readlink -f`. Works everywhere except MacOS X. This comes from FreeBSD, which added `-f` years ago, but MacOS X hasn't resynched its code with FreeBSD for an age, so it's running the version from 2007 or similar. I can show you plenty of examples of this sort.

It would take very little effort to do this on a regular basis, and it could probably be automated.

This creeping incompatibility due to being outdated and unmaintained is becoming increasingly problematic. Not something a regular user cares about, but for development and technical users, it's lacking.
