Actually there are standard metatype annotations as well which work nicely with the new R6 DS annotations. So no need to use proprietary annotations anymore

Nearly none - we have default properties in the scr plugin, so you can configure something like the vendor once in your parent pom and it gets applied to every component. The plan is to indeed phase out the maven scr plugin. It still has some usage, as the bundle plugin is not a dropin replacement. You would need to rewrite your components - and switching to the official annotations has some subtle differences in the defaults. On the other hand, we have a bnd plugin that is able to process the proprietary Felix annotations. Therefore, I totally agree that we should update the documentation. But of course we have to support our user base for some time.
