I'm pretty saddened to hear the scripting got discontinued. It would have allowed people to easily make their own changes and settings, as I imagined
here. Could have been an awesome addition in my opinion.
I don't believe scripting would allow someone to make their own game off Minetest more easily, as anyone can edit the code. Scripted items could instead allow making balancing settings of your own (tweaking functionality of all items on your server). As for the extra dependency, maybe reading data from text files can be done without a scripting engine (like the settings file is read).
Just what I think. Maybe someday, some sort of scripting support will be considered again. I imagine there are other main focuses as well for now, so yeah.
