The reason I ask is because we don't have a good story to tell people right now if they want to add "update" functionality to their RCP applications. This is also evident by Andrew's blog post (http://aniefer.blogspot.com/2008/06/example-headless-build-for-rcp-product.html)... it would be much easier to say "Add this p2 RCP feature" to your product than add these plug-ins and hit "Add Required Plug-ins".
Note that we had this same problem in the past with Update. I believe update.configurator only shipped with the RCP feature and if you needed Update functionality, you would add update.core/ui and that's it. This is more complicated with p2 now and having something like a feature would really make things easier.
Anyone else have comments on this issue and how we effect our downstream adopters?
