The status in MAINTAINERS is consistent with the existing semantic, as there's actually people actively looking after the scheduler (and paid to do so, AFAIK). Wrt the wiki page, the best way of capturing the state of things is, basing on what's in there for the other schedulers, 'Supported' there too. The scheduler has a very limited scope, and is useful only in a handful of situations, and that's by design. But for those situations it works pretty well, AFAIK. Moreover, there is people in the community providing help to interested users on how to set it up (there has been a thread on xen-users about this rather recently). Whether we should recommend to use it in production, well, I think we could, of course for those people and only for them having a requirement for compliance with the ARINC653 standard, which certainly is not the most common thing around. Whether it's actually being used in production by anyone, I don't know... although they may not be allowed to say much/everything, maybe Robbie and Josh could comment on this... but is this that relevant?
