Fictional?! The footways exist and at least on All Souls Avenue are useful for  pedestrian routing.

I spent a great deal of time fixing the decorative sidewalks added by @alisonlung and removing most of them. I did not do that in order for them to be arbitrarily deleted with your spurious justification.

Please revert and discuss your unilateral decision to deprecate separate footpaths in the community forums or Talk-GB.
