Is your feature request related to a problem? Please describe.
I would like to implement a CLI option to have a modular installation as we could see in https://github.com/t3-oss/create-t3-app.

Describe the solution you'd like
I made some PR's in it so I could make a base CLI with some options and write some docs for anyone who wants to improve it

Describe alternatives you've considered
It could use some alternative repos but it would be harder because it has to has some maintainers and so on...

If you like the improvement I could start working on a PR...
