Hi Martin,

As someone who has to update an embedded X11 build maybe once or twice a 
  year, but still wants to pull in other OE changes once in a while in 
between, I'd prefer to see the X11R7.5 includes stick around. There are 
many packages and it's hard for a non-expert to know which versions are 
meant to be used together.
