I agree with you on that point. Merging 13k lines isn't a big deal, we do 
that all the time.

But I don't think anyone in this (or previous) thread brought up the 
number of lines of kdbus as an unltimate argument for questioning or even 
NACKing it.

So I completely fail to see why this is so relevant that you keep 
repeating it.
