Coreutils gets updates regularly! https://gitweb.git.savannah.gnu.org/gitweb/?p=coreutils.git

Even `ls` gets news flags from time to time.

I think "stopping" is great for software that people want to be stable (like `ls`) but lots of software (web frameworks, SaaS) people start using specifically because they want a stream of updates and they want their software to get better over time.
