> "As said by Red Hat's Adam Williamson on the Fedora mailing list, 'That's really a policy decision for the GNOME / Fedora desktop teams, not for ajax. But based on what they've said in the past, I expect that once most hardware that previously needed the fallback mode is covered, fallback mode will die. AIUI, fallback mode isn't meant to be a GNOME 2-by-stealth for Shell refuseniks, it's purely an attempt to accommodate hardware which doesn't support Shell.'"
