That depends on where KLineEdit appears in kdelibs and where attica appears. 
The library KLineEdit is in, kdeui or whatever, could be a Tier 1 or Tier2 
library in the scheme I wrote about on the wiki. Tier1 doesn't mean no QtGui 
or anything like it.

If the attica developers don't actually need the extra completion modes 
provided by KLineEdit, they could make it attica a Tier1 or Tier2 library, 
depending on whether they need something else from kdelibs.

Using KLineEdit instead of QLineEdit does not necessarily provide extra 
functionality if the features it provides are not used.
