man, i was hoping this was going to be a serious discussion on NLEs. instead, we get some niche product of a niche field. i'm not really sure this counts. that's like the team that works for lighting within Unity left to build a new tool that exports settings to JSON.
You're being overly dismissive. There are thousands of people working in such software every day - from serious composers, professional music engravers, orchestra libraians, down to church choirmasters and the like.
It's a several hundred dollar product that supports a dev team in the low double digits. It's niche, but it's not THAT niche.
