> In JavaScript (using a script loader), the same is of course true. Sometimes I need to preserve execution order for dependencies, sometimes I do not want to. But in JavaScript, I have *no way* to choose the ordering behavior. It's *always* "async", even if I don't want it to be. So the only way for a script loader to get ordered execution is to also do ordered loading (ie, serial one-at-a-time loading), which is of course bad for performance.

Isn't this also true for script element created by a parser?  If I set async=false or didn't specify the attribute, then the script is loaded and executed in the order. I'm not sure if we should let it load out-of-order just because it's inserted by a script.  Why should load the resource differently for a script element created by a parser and one created by script?
