I think there is nothing to prove, I set up my prosody just by reading the documentation -- eventually https://compliance.conversations.im/ is a great tool to see how well you are doing, and which modules are worth uncommenting lines from the initial config file. I have a functional and working server with just a score of 85%.

The only real pain point could be iOS, but it is the platform the one that makes things extra difficult, see for example what happens with browsers (https://en.wikipedia.org/wiki/Firefox_for_iOS)
