I don't think you approach is verbose. Personally, I use the "simply
return a local table from a 'module'" by myself and have not felt the
need to do something more sophisticated yet. I even do without your
"read-only" safety measure, thus my solution is even more basic.

Using Lua as an extension language, the main benefit of this maybe
most basic approach is that it is explainable to inexperienced and
temporary co-workers.
