Hi

I've noticed highway=footway is being used as an area across Lambeth Bridge: North side as a closed polygon; South side within a relation. (checking the history previously they were both highway=pedestrian.

Regardless of whether it's mapped as a footway or as a pedestrian area it looks like a fairly extreme case of "mapping for the renderer with no thought given to map usability". If you look in the area of this node:

http://www.openstreetmap.org/node/2622468074

The data as it exists now suggests that there's no access west from this "footway island" to the pedestrian crossing across Millbank, or actually anywhere on the west bank of the Thames. This pedestrian island functionally duplicates the "real footway" http://www.openstreetmap.org/way/256600109 (from which you can get north and south, though not west)

I'd be in favour of a similar linear / area split as there is with rivers = "waterway=river" - is the line of the river for e.g. routing purposes; "waterway=riverbank"the outline of the bank which can be used for rendering but ignored for routing.

Cheers,
Andy
