Since I'm not really active in Elgg development lately, I wanted to bring up some unfinished projects of mine, that someone might find useful. One of them was making community plugins repository contents installable via composer to make managing complex Elgg installations this one bit easier.

System basically works, but wasn't tested in depth. It's elements are:

• satis built repository https://github.com/Srokap/plugins.elgg.org that is deployed at plugins.elgg.org (though SSL cart being broken, prevents you from reaching it)
• it is updated via cron using https://github.com/Srokap/community_satis  plugin on community here
• To use it you need to add additional repository to your composer.json and that's it. You should be able to just define plugins defined at plugins.elgg.org as dependencies

Mechanism doesn't work for plugins with unusual version strings and for .tar.gz files (composer doesn't handle it well).

If someone was interested in picking those bits and using, feel free to do so.
