I think the rules for which (temporary vs not temporary) to use should be application-specific. And the people who are best-positioned to determine what's right for the app are the app developers or designers. Not IETF.
I vote for 3484bis to remain silent as to a preference, but to provide guidance as to what might cause an app to select one address over the other. Apps that aren't designed for Internet access (e.g., UPnP, enterprise applications to run on corporate devices inside the corporate network) have no need for temporary addresses, and may find that they cause a bad user experience. Apps that register their presence with a server (like a SIP registration server) are ill-served by temporary addresses. Apps that need to be able to receive unsolicited traffic shouldn't use temporary addresses. On the other hand, I think I'd prefer if my web browser did use a temporary address, if that feature were enabled on my device.
