It depends. Mostly on what kind of users you might have.

If the underlying model is very powerful but so complicated that it's very difficult to convey it to anyone, is it of any use? "Financially lucrative" in that case is simply a proxy for "can I get anyone go understand what is even going on?"

I've built an online pub quiz, and I'm doing as much hallway usability testing (in the Zoom hallway) as I can. Early on, every single one ended up with me changing things from being more flexible and powerful to being simpler. Either the underlying model, or just what is being presented/allowed in the user interface at any given time.

There is just no point in trying to provide lots of options instead of a well thought out middle-of-the-road path of obvious next steps if no-one will be able to get around to doing what they came for. People can't become power users if they aren't users.

UX design is so hard, but luckily it's also very interesting :)
