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?
