There are environments which require a lot of tooling and automation in order to be productive. Integrated platforms like Android, iOS, or Visual Studio come to mind. These require so many configuration files to be kept up to date, build tools to be run in just the right order, and projects to be organized in special ways, that they are all but impossible to work with outside of the official IDE. In those cases, I prefer IDEs with some kind of Vim emulation over Emacs. Other environments are less restrictive, and projects often come down to just a bunch of files in a git repo. This is where text editors shine. I consider this a language feature of sorts.
