+1 never used it.

I also did not manage to find a server where $_SERVER['SCRIPT_NAME'] would be undefined.

@dg Can I remove the URL filters? They are magical and people who know about them prefer to turn them off anyway – see http://forum.nette.org/cs/9903-ne-kanonizace-lomitek-v-url or https://twitter.com/JanTvrdik/status/542389794085404673 Or does it fall into the same category as binary mode?

ad $_SERVER['ORIG_PATH_INFO'] & $_SERVER['SCRIPT_NAME']: detection is magic. See this versus this. Currently it somehow works and it is better to not touch it ;-)

ad filters: their problem is that they do not work with canonicalization... Filters are not used because nobody knows about them, they are hard to set, but they are useful. For example, they fix bad url parsers (like this), so it would be better to figure out how to solve the canonicalization.

ad filters: I'm aware of what they can do, I'm just saying that nobody is using them for that. Even your websites don't use them. Wouldn't it be better to handle those use-cases in routing instead of RequestFactory? Or not handle them at all?
