Pretty much. I’m a plugin developer for Decky Loader on Steam Deck and my sole motivation is I enjoy building cool shit. I wanted a feature on my Deck that didn’t exist…so I just made it. Then, since others wanted the feature I created a pull request to the Plugin Store so everyone could use it.
I’ve spoken with quite a few of the other Steam Deck Homebrew developers and they basically all had the same story. It’s also nice because if you get stuck or need help there are hundreds of people you can ask who are very knowledgeable, and more than willing to help.
