[openstreetmap-website] Related objects in XML (#768)

[Paul Norman]

Failed preconditions aren't an issue with delete if not used. With splitting, yes.

As for impact, it's an additional join against way_nodes to backfill and at that point it's basically not different than a `/full` call in SQL required, with obviously less bandwidth.

To better understand the queries, it's probably easiest to look at cgimap, which has clearer queries.
