I see that in Factory, Alternative Status Menu is no longer installed by default. Although GNOME 3.6 finally provides "Power Off" by default, without Alternative Status Menu it is *impossible* to Hibernate (without resorting to command line). You can't press Alt to get Hibernate like you could for Power Off before - you just cannot do it.
Moreover, Alternative Status Menu v3.6 no longer provides Hibernate by default. The extension still supports Hibernate perfectly fine provided it is configured to do so via gsettings, but if you install the extension from extensions.gnome.org, then it will use a private gsettings file that Dconf Editor cannot see, and you're basically out of luck unless you really know what you're doing. So this has to be an openSUSE package, rather than something installed from extensions.gnome.org.
I've done the work of updating the extensions package and our default gschema overrides and filed SRs 146537 and 146538 for this. If those are accepted then anyone installing the extension with zypper or yast will get Hibernate and be fine, but I'm aware that we don't normally package extensions unless they're installed by default, so I sent this email to:
1) Explain why we should package this even if we don't install it by default.
2) Suggest that we should continue to install it by default. :-) This isn't covered by my SRs, and I don't know how to do it anyway.
