Deploying Launch async - alternative tag syntax

So this new feature to deploy Launch async.

I see that it gives you a tag like this:

<script src="//assets.adobedtm.com/launch-12345-development.min.js" async></script>

From my perspective, I should be able to instead do something like this:

(function() {
  var s = document.createElement('script');
  s.src = "//assets.adobedtm.com/launch-12345-development.min.js";
  s.async=true;
  var t = document.getElementsByTagName('script')[0];
  t.parentNode.insertBefore(s, t);
})();

I want to be able to do this because it would allow me to dynamically output "12345" and/or "development" parts of the script URL - something that has been a sore spot with DTM for a lot of people.

Will Adobe support async deployment of the Launch script like this?
