All of your request are there for your personal use if you want them. If you need a modular extension there is HMVC and you can go for it.
You want an ORM? There is Doctrine (is really great), Data Mapper and DMZ (Data Mapper Z Edition).
GET? use $this->input->get() and that's all...
I think CI is a great framework, would be great to see it in PHP5 but nothing more (and I know it wont happen so I don't care and I'll continue using it anyways). All the 3rd party hooks/libraries/helpers/ and modifications are if you need some of them.
btw, RTFM next time
Cheers..
