Ah sorry for not being very clear.
We dont need to load the URI library since it is autoloaded by CI. If you tried to do $this->load->library('URI') PHP will report an error. This also applies to the custom MY_URI library. It will be autoloaded by CI - there is no need to load it.
Yes, this is a nice solution - and I think this feature (multiple url suffix) should be included on next CI release!
