There is https://wiki.openstreetmap.org/wiki/Proposed_features/hail_and_ride which should apply to the W5 route along this location, but the stop itself is tricky.

TfL has a point feature for a bus stop here, which has some uses like announcing the next "stop" on the bus, and tracking arrival times. If these virtual stops didn't exist there would be 2.5km of "hail and ride" gap. There is the occasional bench along the H&R section, but these are not aligned with the TfL locations, so should just be marked as normal benches.
