Hi! Thanks for asking. This neighborhood was one of my Pet Projects. I had just started OSM, and barely knew anything (still don't know a lot lol), and I added the walkways from the main sidewalk from into houses as extra details in the map. I've realized now that they serve no purpose, and don't affect any navigational systems, and nobody else had added them in other neighborhoods nearby. For the sake of consistency, I removed them. If you would like me to add them back, let me know! Also, since I m still learning, please let me know if there are any changes I can make to improve my mapping skills!
