However, the resoning ought to be, what is a strong concept and well doable with the current code base without bloating it? In this case it is not.
Not, "I don't need that in my field of work, so I just suppose other don't as well." Or do you have a scientific method on operationalising how often other people need this or that with their way of using Lua?
