It does 99%+ of running a side business for me that otherwise wouldn't possibly be profitable because the margins would be negative (no, I'm not going to go into details because the moat is too small and I'm just taking the profits I can until the window closes).
It also added functionality to my terminal that I didn't have time to add, and added functionality to my window manager I wanted but didn't have time to add, both of which improve my general quality of life - I spent 12+ hours in front of my machine a day, only part of which is work, so ergonomics matters.
