That still doesn't explain why you think it isn't BIC. Say, in module kdebar 
there's an app KFoo shipped with KDE 4.0 linking against kjsembed.

If you upgrade kdelibs *only* to 4.1, by definition of BC, all installed apps 
for KDE 4.0 must run unaltered. However, as kjsembed vanishes with the 
upgrade, KFoo linking against kjsembed stops working.

So why is removing a library BC just because it isn't referenced in 
a .la-file?
