I'm the opposite; I don't stick much time into learning a language if it doesn't have a high quality vim plug-in and command line tooling. It's fairly shallow, but I want to learn how things work behind the scenes, and I don't like fighting the editor over my preferences. It's a lot of small things, but why not enjoy your hobby time? This is just my personal preference and I understand and respect that there are lots of folks who enjoy their IDEs like I enjoy vim/Unix.
