I think it's more important to let the compiler not to compile unused resources

Are you talking about unused arguments elimination?
IMO, such optimization is pointless as it is almost never useful in final code.

On the contrary, debugging of incompletely-written-functions is a common case.
It is usual practice to comment out some parts of function's body while searching for programming mistakes.
As a result, some arguments may become unused; and message like "vararg: empty" (instead of list of actually passed values) in Lua debugger would be very misleading.
