Should I use common::sense or just stick with `use strict` and `use warnings`?

Question

I recently installed a module from CPAN and noticed one of its dependencies was common::sense, a module that offers to enable all the warnings you want, and none that you do

Answer 1

The "lower memory usage" only works if you use no modules that load strict, feature, warnings, etc. and the "much" part is...not all that much.
