Making custom menus for mods

Wait, what?! LUA support got removed? I’ve completely missed that. I probably have to change some of my answers then…

Is there a topic (on discourse) with some discussions on that that I can dive into? I just found one really talking about it.
Don’t get me wrong; from all the languages that I know and use, I detest LUA. I even prefer to code in assembly, regardless that I’m a bit sh… uh… slow on it. So I’m a bit gloating. I was just wondering if it’s really that efficient to have a lot of git pull requests for such stuff (and also get a way to better unterstand the reasoning behind it).

I guess it’s possible to do it in C++? Or is that off limits?
