True, but maybe the stream use cases don't require that? Maybe it is more important for an application to know in an instant where something is being edited, than having complete knowledge of what has been edited yesterday? I don't have a killer app in mind where I would say "this works with a stream and doesn't work with minute diffs". But I can think of a number of applications that would be cooler with a proper stream. I mean, just look at Bernhard's application: http://datenkueche.com/osmlive/ It looks very cool and you have the individual spots lighting up in something that looks like "real time" but then it is five minutes delayed and based on chunked diffs - meaning what you see is a fabricated replay of what has probably happened, and not "the real thing". Which diminshes the coolness, if only slightly. Now I'm not saying we should turn the database inside out to support fractionally more coolness. But saying: "We don't intend to support this because we cannot think of an application that absolutely requires it", is quite un-OSM, is it not?
