The original extension author really hated the app switcher with a
passion and took over all its uses, but there's really no reason
to replace the 'switch-group' shortcuts - not least because the
window switcher doesn't implement switching between windows of
a single application. So just keep the extension to making the
'switch-application' shortcuts behave as 'switch-windows' for the
"classic" session (and all users who rather install an extension
than change shortcut settings).
