As a mod on webmasters, maybe I can shed some light. 

`.htaccess` and `mod_rewrite` rules are a real grey area, even on the webmasters site. Our definition of a webmaster is someone who takes care of the day to day running of a website, which does NOT include:

- Server configuration
- Apache/IIS installation
- Apache/IIS configuration

As these are generally taken care of by a sysadmin. Basically, if it's something your hosting provider takes care of for you, then it's not a webmaster problem.

But you raise an interesting point. I will start a meta discussion over there and try and bring it up again.
