Hi Zac,

Apologies for the delay and great to hear that you love Java!

1] Importing in that way will ensure that the necessary files are included into the production bundle. All Vaadin components with Lumo support have the same imports, which means that you'd have to manually change all of them to use a CDN if you'd want to avoid loading duplicates. The Lumo files are indeed served from a webjar, but they are referenced in a non-webjarish way so that the same implementation can also work for those who don't use webjars.

2] Lumo theme is open source. Business App Starter is a part of Vaadin Pro license (commercial).

3] Yes, this has been discussed heavily as it impacts the Developer Experience with our framework. The unofficial fix for this is after V14 launch.
