KDE4 packages are into usable form, what we miss:
* copyright files, which is awfull and is a time killer.
* upgrade path
* kdelibs kde3/kde4 co-installable
* not uploaded anywhere

but it's probably because we want something ready to use for experimental (at 
least, this is my POV).

a one-line calling 3 others files which are not  a one-line rules themselve.
it hides other files and make dig into other files to find what we want (it 
reminds me cdbs nature ...), when i found a single file more readable 
especially a ten-line.

i don't think it's premature. i submitted the cmake.mk one year ago, and play 
with kde4 since around 4 months. Sincerely, i don't think there will be more 
fine-tuning compared what we have now: something easy to use and 
understandable by everybody. And i doubt there will be many improvement now.
