I think it is safe to say that Twisted is more widely used than anything Google has yet released. Twisted also has a reasonably plausible technical reason to dislike this change. Google has a bunch of engineers who, apparently, cannot remember to create an empty __init__.py file in some directories sometimes. > >I was a pretty strong -1 on the original proposed change of allowing >import on empty directories, but my take is that if a project >deliberately includes empty directories, they can add a new warning >filter on program startup.

The usage here precludes fixing it in Twisted. Importing twisted itself prints a warning: there's no way to get code run soon enough to suppress this. I do think requiring each user to modify sitecustomize is overly burdensome. Of course this is highly subjective and I don't expect anyone to come to an agreement over it, but it seems clear that it is at least a burden of some sort.
