The Badge component is currently an experimental feature and needs to be explicitly enabled.

1. Are we going to release 2.0.0 while Badge is an expertimental feature, or will we wait until it is stable?
2. Applications using version 2.0.0 of the add-on need to enable the experimental flag. We need to document in README that:

The Badge component is currently an experimental feature and needs to be explicitly enabled. The component can be enabled using Copilot, in the experimental features tab, or by adding a src/main/resources/vaadin-featureflags.properties file with the following content: com.vaadin.experimental.badgeComponent=true

3. Add vaadin-featureflags.properties as a JAR exclusion. (Currently, it's in the repository under src/main)

1. I did the update assuming all knew about it. So for me it would be okay to release it as experimental (I'm not sure when it is going to be a stable feature in the framework).
2. I missed that in the implementation, it should be mentioned in the Readme.
3. Good catch.
