How to make it a "Framework with a small footprint" again?

Thanks for the hint. This is what I was looking for. But I still have a question:

I did:

Code:

composer create-project codeigniter4/appstarter

composer update

composer install --no-dev

Then there exists a directory appstarter/vendor/codeigniter4/framework which holds the same directory structure as appstarter (app, public, writeable,...), but additionally the essential system directory. Can I savely delete everything in there except system (and maybe the other directories in appstarter/vendor?. Would reduce the footprint more and remove useless (?) dupes.
