Why make it hard when it can be easy?
shirock wants urls like blogs/index, blogs/index.xml, blogs/index.pdf. CI makes it possible not to use the default function which means less typing for the users.
Louis w the extension is located at the end so why do you want to add it as a prefix?
Coding standards state make everything as readable and as short as possible this is also the case when you set up a url schema.
