For it to work well the developer has to change the game's design to allow for the easier mode to work. If they don't, it wouldn't offer a good experience for neither the easy mode nor hard mode players.
From a purely financial view, they don't. There's a reason why games have become as handholdy as possible. And one of the reasons why the Souls series stood out was because it went in a different direction.
Maybe? I feel like the developers have the prerogative to decide to include it or not, but with the way the discourse has gone it certainly feels like I'm in the wrong here.
I thought about it a bit when making this post and I felt like not giving an example would make people come with crazy political opinions which would probably be a bad time. Maybe it still wasn't the best approach, admittedly.
I don't particularly find the acessibility argument that compelling. Sure, we must make experiences as acessible as possible, but at a certain point the experience gets degraded by it. You can't make a blind person see a painting, and if you did, it wouldn't be a painting.
Niches really need a way to advertise themselves and then congregate in one place. It's a bit sad to see two communities for the same thing in different instances and neither get the critical mass of posters needed to survive.
One aspect I feel is never talked about is that setting up the debugging more often than not takes you out of the mental space of the problem you are trying to solve. A console log is basically there already in many cases.
Poorly received games with tons of other venues of monetization outside the box price.
