Rest assured that for me it's not even imaginable to break 2.2 with
such sort of things. We have sufficient issues to address right now!

Be careful that nginx is a web server, not a gateway, so it doesn't have
to care about how the next hop would interpret the request since there
isn't such "next hop" so it only has to be consistent with itself. And
by the way, in case you'd still use it as a reverse-proxy using proxy_pass
you have to be aware that it only normalizes during analysis but forwards
the unprocessed request, leading to some of the well-known things I


This article by the way also mentions the funny things with some
application servers which incorrectly use ";" as a query string
delimiter, which is yet another thing breaking normalization!
