[Owncloud] App developers: We will deprecate use of %webroot% in CSS for ownCloud 7

[Bernhard Posselt]

I like the move to seperate icon classes since it covers the base 
usecase. If you use more complex backgrounds like maybe background image 
and color this may cause issues. Then again this should be very rare, 
should the app dev just create a local copy inside the app?

Maybe a solution without breaking backwards compability would be to not 
remove the feature but document the usage and available css classes 
better and fix the core apps (some devs look at example source instead 
of docs). This would improve performance loss (again if its not already 
cached) to a bare minimum.
