I didn't want to express any opinion on the change; I use aiohttp for my python-powered web-scale crawling needs. So yes, it's accurate that I was warning that the change would be incremental and not a panacea. BTW aiohttp has the problem of currently having a too-strict http protocol parser, so it throws errors for many rare cases of bad webservers, which browsers don't have a problem with. As a crawler, I need to be able to work with whatever a browser will display, ... |

I've been interesting lately in exploring at aiohttp, and your comment about it being too strict is certainly very enlightening. And I want to second your comment about libraries following the lead of what browsers will do. My strong feeling is that the battle over what HTTP libraries should do has been fought and been decided by browsers, and that whatever browsers do is what HTTP libraries should do as well, regardless of how ugly it is (IIRC, when I last checked, browsers did pay attention to the Content-Length header and wouldn't display results that were shorter than it - but if I'm misremembering, I would happily change my position with respect to honoring this header). The purist in me hates to say that, but, the pragmatist wants to get things done and fighting against browser behavior feels counter-productive at this stage.
