Many thanks for your comments.. I am indeed working with Waymap, but this is not part of any organised activity.
 
I am in the process of investigating turn by turn instructions,  this will involve me modifying a local copy of OSM rather than the public version.
To understand the processes  of generating missing sidewalks and naming them I was exploring the Shepherds Bus OSM area , and made some corrections for consistency , Indeed splitting sidewalks that traversed intersections was one of the errors I was hoping to correct ... I will investigate the particular example that I missed , and will revisit the Sidewalk attributes of the roads... I did not create any new sidewalks , but accept that I can correct the associated roads which may have been incorrectly attributed when the sidewalks were generated in the first place.
 
To confirm it is not my intention to enhance the public OSM on behalf of Waymap  or extend any of the previous Waymap initiatives , but I will  diligently fix any historic issues I encounter
