On the contrary, my point is precisely that all the new good habits of
avoiding pollution of the global namespace is undermined by the Lua5.2
interpreter itself.

The present behaviour is this:

~~~~ mymod.lua
return 42

    $ lua5.1 -l mymod -e "print(mymod)"

    $ lua5.2 -l mymod -e "print(mymod)"

I.e. the global name is not created by the module, but by the Lua5.2
standalone interpreter.
