But HTTP's GET is about downloading, isn't it? Or can you tell the server 
something like "Ooh, sorry, I do not need the rest of the information"?

I do not know if it is "preaching to the choir".

KIO is a point that personally I would like to see strenghtened, not weakened 
in KDE4 (especially that weakening KIO would give fuel for people being 
against Konqueror and KParts).

Well, from the bugs that I remember of KIO, such problems could appear with a 
single application. So if we go on the way of "each KIO slave is 
independant". I suppose that we will get more of such bug reports. It would 
be especially worse if such bugs are especially on non-Linux systems, as 
developers for debugging such kind of problems would be rare.

Have a nice day!
