Is "Leigh Hunt Street" still legally a street here? If it is, then shouldn't it be listed here on OpenStreetMap? Google Maps seems to think that it is still legally a street here: https://www.google.com/maps/place/Leigh+Hunt+St,+London/@51.5025,-0.0970554,19.25z/data=!4m6!3m5!1s0x487604a7b304c4ef:0xf1a554fd618ee060!8m2!3d51.5026002!4d-0.0966989!16s%2Fg%2F1tg80yj4?entry=ttu
