The release of RHEL 5.9 also means that the development of RHEL 7 is heading towards final stages. Based on previous patterns of Fedora and RHEL releases, we will have the (much delayed) Fedora 18 as the base for RHEL 7.
As such, we will most likely have Gnome 3.6 as the default user interface in RHEL 7, which will have support for 10 years. This should set off alarms.
A curious mind might well ask:
(i) will the Gnome extensions (that make the desktop usable, ie. classic mode) for Gnome 3.6 be _stable_ and available _online_  for 10 years?
(ii) if not, will Red Hat provide the appropriate subset of Gnome extensions as a standard package in RHEL 7 ?
(iii) if no to (ii), is Red Hat going to improve the fallback mode in Gnome 3.6, so that it is on par, in terms of functionality, with Gnome 2 in RHEL 6 ?
While the Gnome project recently announced that it will include by default a stable set of extensions that enable a "classic mode" , this only seems to apply to Gnome 3.8+ (ie. Fedora 19+). This is a problem, as Red Hat is not known for changing the Gnome version in RHEL once it has selected a Fedora release as the base (ie. Fedora 18 in this case).
