He's saying supporting it wouldn't be a complete waste of resources. Besides 1) What's a showstopper? No support or somewhat weak support? 2) When do you suppose people will be intrested in Haiku? Right now, with normal features? Right now with advanced but incomplete features? Or in the near future where Haiku is the only other end-user OS with the features of tomorrow? I think the priorities are: 0. Security 1. Operation. It must work, at least somewhat. All of it. 2. Reliability and feature completeness. This approach has the release early release often advantage. I'd never hurt of the new Linux storage system though. Prioritize those most likely to be used/required the most often before the alternative can be made.
