I'm saying the framework doesn't have support for parallel tasks within a single request. For example, the case of kicking off two database queries in parallel, then doing something when both are finished. I understand that each request executes in parallel.

It's possible I missed how the framework supports parallel tasks, can you explain? The only thing I saw was wait(), which gives you "series" instead of "parallel". It's true people could still use callbacks/libraries to implement parallel tasks, but then we haven't gained much.
