I think the assertion of many here is that the web developer *can't*  
have any knowledge about whether or not the operation will happen  
quickly...
If the application's solution is to handle timeouts and try again  
later, what if their execution environment doesn't change?

Such as the user is playing a system-intensive game, or transferring a  
large amount of HD video, or any other disk-intensive task that is  
long running.
Or the user is on limited power device that will always be slower, and  
the query the application is trying to execute is *just* over the  
timeout threshold, and it will never be fast enough.
And I can think of a lot more!

This application will never succeed in storing its data, and the  
developer/user won't have any recourse.

In this case we've given the application developer the tool to shoot  
themselves in the foot and they won't even know it.

I don't see the advantage of replacing a targeted form of  
asynchronicity that has some consensus with a general purpose form of  
asynchronicity that brings a lot of other concerns/debate along with it
