As a relatively new member of the Cloudron community (especially compared to @scooke) I can see both points of view. The current collection of apps is very eclectic, spanning both personal and business. And to a certain extent that reflects the wide range of our community - a strength.
I do not envy @girish and team trying to please all of us. It is both thankless and impossible. But one person's "must have" app is another person's "who cares". The danger is losing members if their needs are not met with the applications they need or want.
Perhaps having a simplified installation process would allow more people to customize their Cloudrons as desired. And yes, despite the warnings that you are on your own, I am sure that support questions will arise. And the spirit of the Cloudron team and the community to help will always prevail. As long as these questions are within reasonable limits, perhaps this will allow the platform to grow more valuable without being overwhelmed. I would suggest that custom-installed apps have its own topic area, especially if the results could be hidden from search engines to prevent prospective members getting the wrong impression about Cloudron's reliability per @scooke 's valid concerns.
Finally, I am personally interested in a business-oriented, custom-app platform where Dockerized applications can be hosted in a well-thought out and architected environment like Cloudron. We are exploring several ideas along these lines, including adding some private applications we have created, others we have paid to license, and some that are open source. And these systems would require incremental Cloudrons - helping to grow the revenue stream. In the end, that's the idea, isn't it...
