I think the title explains it pretty well. Right now with RCON, you can call MC commands, and that's it. I think that Paper should have the ability to connect the API to RCON, mainly for cross-coding language support. Even though it wouldn't be quite as efficient as a true plugin, you can now pretty much make a plugin with any language that supports TCP connections. So basically, almost every language. I think this would push Paper over the top as the best server platform for developers, and just a well received change in general. Thanks for reading this, hope it's considered!
