Fibers-agnostic context-handling wrapper? Has it been written yet?

When looking at some code that uses fibers directly, it seems there should exist a wrapper library that uses fibers for implementation when available and otherwise does whatever is the replacement that preserves the context for callbacks (asynclocalstorage?)

E.g. from picker/implementation.js at master · Meteor-Community-Packages/picker · GitHub

PickerImp.prototype._processRoute = function(callback, params, req, res, next) {
  if(Fiber.current) {
  } else {
    new Fiber(doCall).run();

  function doCall () {, params, req, res, next); 

How can this code be written in a fiber-agnostic way so that it works both in 2.8, 2.9 and 3.0?

We’re already working on something in this line. You can check it here.

Are you modifying something and creating these wrappers?
