A plugin system in no way impedes having a set of curated and polished features out of the box. It simply allows the addition of new features to have the same status and be part of the same class as existing features. It's an architectural and design property of the system, not a property pertaining to quality.
In your case you can stick to installing plugins written by first parties or write your own plugin for specific use cases that you come across. You don't need to have any use cases for plug ins right this moment, but perhaps at some point if you find yourself repeating the same manual process over and over again, you can write a plugin to automate a substantial portion of it.
