I agree that the OStatus project should take a more active part in this as questions about the deployment status of the specs really is a concern for OStatus in general and some projects like StatusNet in particular:
http://www.ietf.org/mail-archive/web/apps-discuss/current/msg05081.htmlThe recent discussion on the backwards compatibility of Pubsubhubbub 0.4 has highlighted the issues of transitioning all OStatus sites to newer non-backwards compatible specs:
https://github.com/pubsubhubbub/PubSubHubbub/issues/12Transitioning from WebFinger to SWD would probably be an even bigger challenge than transitioning from PuSH 0.3 to a new non-backwards compatible PuSH 0.4 - especially since the OStatus group as far as I'm aware still is using the pre-draft versions of WebFinger and thus it isn't as easy to transition as if one would fully support the latest WebFinger draft with the new resource query parameter and all:
http://www.ietf.org/mail-archive/web/apps-discuss/current/msg05118.htmlI think that the OStatus specification should be updated to better specify which versions of all specifications that it expects sites to use to make it clear that any future backwards incompatible changes to those specs, be it PuSH, WebFinger or something else, isn't part of that particular OStatus specification and that it would be up to any possible future OStatus version to define how they should be used and any transition to it.
And as I said initially - the OStatus spec should be more active in these other discussions and making the challenges in introducing breaking changes to OStatus clear to everyone involved.
