Prosody dev here. Good to know this is useful :)

One of my favourite small features we added in the latest release is a 'prosodyctl check features' command which will validate that your configuration is up to date with current best practices in various ways.

Although we like to curate the default configuration with care, people tend to keep their existing configuration file when they upgrade (we generally recommend this, as we aim for backwards compatibility). The new command makes it easier for folk who upgrade to ensure they are still getting the expected experience as the recommendations evolve.

Obviously that has to be somewhat opinionated. One thing many people appreciate about Prosody is that you can customize it however you want to, even if it's not following the mainstream. E.g. if you really don't care about synchronizing to multiple devices, you can totally disable that message cache. Don't need audio/video calls? Fine!
