Keyboard shortcut definitions could specify a condition to determine
whether it should be shown in the UI or not. This was only used by
Metacity/Mutter, to make the visibility of some shortcuts depend on
the number of workspaces. However, as workspaces are now managed
dynamically in GNOME 3, the frequent changes to the list of shortcuts
have become rather confusing, so a fixed list of shortcuts is used now.
With the only consumer of conditional shortcuts gone, there's no reason
to keep the feature around.
