Unfortunately this is some external requirement I cannot do anything about. Also, as opposed to many people, I actually got to work and know both the IDE-world (including VScode), and the vim world. I have a base for comparison.
There are also times when the available bandwidth is limited, so just having to use fewer keystrokes to edit a file speeds up the process. I was able to connect to remote linux servers over dial-up and edit files on those servers with vim without issue. Editing and saving over ssh was more of a hassle since it took longer to save the file (and I save pretty often).
