Those that want that can do it themselves:

local ogsub = string.gsub
string.gsub = function (a,b,c,d)
  if type(c) == "function" then
    local oc = c
    c = function (...) return oc(...) or '' end
  end
  return ogsub(a,b,c,d)
end
string.repl = ogsub

No need. Just use the compatibility code above.

Well, we do not intend to change that.
