Personally I'm very reluctant to the idea of changing the includes. The risk of us having to hunt down breakage for weeks is IMHO way too high for the possible benefits. We just had it too often during the frameworks transition that a header file got renamed, missed in one place and it starts to randomly break to compile on some systems because a kde4 header is picked. Then we easily waste huge amounts of work power on people trying to fix their build. That's also the reason why I decided against renaming the headers for KWin. Just my humble opinion. Cheers Martin
