Thanks for sharing your thoughts and trail theory BPTT! I agree with most of your thought process. I also agree dead-end paths and playground access paths that are not primary cycle routes should be considered for foot path tagging too. For paths that connect or "dead-end" with a parking lot, I challenge your default foot path designation. Sometimes exiting a cycle route thru a parking lot is ideal. For connecting parking lots to trails for foot traffic I started to utilize the "access aisle" footway tag to be more specific and accurate than foot paths connecting directly to parking lots. Again I agree with most of your mapping theory but wanted to make this call out because I've noticed missed opportunities for cycle direction algorithms.
