I've been 'exploding' several building nodes into ways, based on splendid Bing imagery for Bristol.
It is nice, isn't it? I've been lucky enough to have 25/30cm imagery from USGS in most of my area, but this 6cm stuff is awesome. And cheers to the implementation for JOSM - it's incredibly fast and agile. Truly an important step for OSM.
I'm getting concerned about data loss, the fact that any external database accumulating information on such vulnerable nodes, e.g. [1], will only with difficulty and guesswork be able to match it to the way that replaced it.
I favor using the existing node as part of the new way, then removing the tags from it. This preserves its history. However, I don't believe people should ever count on OSM IDs to be at all permanent - they aren't designed to be. There was a long discussion a while ago about using GUIDs for that if necessary.
