This particular point does depend on the order of require() calls, of course.

This is good defensive programming. These are good points, and the extra effort is (a) worthwhile and (b) mostly automatable.

As for assert(setmetatable), it's less painful to make this a 'compile-time' problem with an appropriate static analysis tool.  And I suspect that the 'luac' trick could be covered as well.
