Linden Lab's Rob Linden has encouraged Second Life developers to bring forward issues with the proposed changes to login arrangements. Particularly he has invited a formal, group critique on the proposal "incorporating the salient points ... expanding on some of the earlier points ... and providing a list of questions that you'd most like addressed."
That critique is forming up on the Second Life wiki now. From monitoring the chatter on the development mailing list, I've yet to see anyone who is in favour of the proposed changes - and most tellingly most people seem to see the move as introducing an added level of security risk over and above what is present with the existing scheme.
