With version 2.4.x, Magento includes about 200 internal PHP packages plus more than a hundred external PHP packages. These numbers have grown a lot in the last few releases, especially with several packages for the GraphQL integration and for the Multi Source Inventory. Magento 2 has a lot of built-in modules that provide different functionality, but you don’t need to use all of them 100% of the time. This means that you can safely disable elements of the platform’s modules to give performance. You’ll achieve better performance, and your admin users won’t have to deal with superfluous functionality that isn’t being fully utilised. Maybe it would be useful to prepare a list of core Magento 2 modules that can be disabled with no harm for your store, because they are hardly used.
