All components in the generics folder that are prefixed with Base will be globally available and don't have to be imported. But: changes made to these components will only be visible when rebuilding the frontend! (So when you work on BaseComponents make sure to import them like regular components temporarily, to see changes reflected immediately.)
I only copied the icons we are actually using in the app, so instead of more than 600 we now only include 65 icons in the project. To add more icons when you need them just copy-paste the .svg file from the styleguide into the /assets/_new/icons/svgs folder! (I'll try to find/set up a good way to search all available icons.)
Files to review
A ton of files changed just because...
I replaced <ds-icon> with <base-icon> --> many .vue files can be ignored,
pasted the svgs from the styleguide --> all .svg files can be safely ignored,
and changed the localVue import in all test files --> all .spec.js files can be ignored
