I think this is a similar case as nepomuk. If its completely outside of
kdelibs app developers are not aware of it and thus will once again end
up with their own solutions (possibly hard-coded colors) and even if it
is introduced in 4.1 that doesn't mean that app developers automatically
port to it if "their way" works well...

In particular KDevelop will use both the blending and the new color
roles, for example to highligh compilation errors and warnings - the
latter needs the blending because there's no warning color role, I'd
like to use a blend between error and the background for warnings. I
think the same will apply to the extra highlighting that kdevelop does
(on top of kate) using its parsers.

I guess kate can also remove some of its color-stuff when this is in
kdelibs, although maybe not everything (there are quite more colors in
kate syntaxhighlighting).
