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

perhaps after your  composer no dev install you run  :

Code:

composer require codeigniter4/shield   

https://packagist.org/packages/codeigniter4/shield

If using "composer require codeigniter4/shield" then got:
  Could not find a version of package codeigniter4/shield matching your min 
  imum-stability (stable). Require it with an explicit version constraint a 
  llowing its desired stability.    

I see only one way to avoid this with bring devs packages with "composer require codeigniter4/shield:dev-develop" but I'n that case framework on my disk have about 32mb.
