Bundler and development server preferences

Playing around with the new Rails 3 beta and one thing that struck me is that to use mongrel as your local development server you need to specify the gem requirement in the Gemfile before the rails server command will notice.

I know you can create a development group in the Gemfile that will isolate this but since the Gemfile is going to be under version control this essentially forces the same preference on everyone working on a project.

Is this the intention or should I create a Lighthouse ticket?
