@crisvdn Thank you for bringing up the subject. I’ve also been thinking about this for a while and have some ideas.
I try to keep the official module list up to date. I do reviews of modules and create PRs. Many are accepted, some are ignored.
I’ve started working on a new list of modules, and doing some rudimentary tests (you can see the result here). A few developers have already started work through the recommendations there. Even though the whole project is still in its infancy, but with that we have a process of assessing the quality of modules. Perhaps the whole thing will develop in the direction of module installer or app store. We will see. I would be delighted if you would take a look at the project and maybe join in.
There are already some great other approaches - for example the package manager mmpm or the “app store” in MMM-GoogleAssistant. Surely such projects could be combined on some level. I’m currently focusing on making my approach more efficient, then it’s time to automate it with actions.
