Well, this does not exactly give a rationale.  It just says that this
is unlikely to change for what appears to be technical reasons.

Whether those should win over usage consistency is a different
question in my opinion.

As it is, one has to change

function()
  for i=1,select('#', ...) do something(select(i, ...))

to

local args={...}

function()
  for i,x in ipairs(args) do something(x)

and this seems somewhat unelegant.
