I do not expect xlib to ever go away. There is so much written for it, 
its sort of pointless to refactor apps "because we can". If one makes a 
new app, XCB may be a good choice, when it is mature. I am not sure what 
benefits XCB has however. It could be as well, the way things often go, 
someone will forget some needed feature in XCB and Xlib may end up being 
a better choice in some situations. Ive often seen things like that 
happen. Case in point ., i upgraded t KDE 4.0. The new Konsole does not 
take the escape codes for setting the title bar with program name/path 
name i have sent by tcsh precmd and postcmd. I deleted KDE 4 and went 
back to KDE 3. Someone didnt understand the importance of this and didnt 
include this. KDE 4 for me was a downgrade, it actually regressed.

An age of code is no indicator of its quality. Old code can be better in 
cases. Consider most modern applications such as Firefox which are 
bloated memory hogs compared to older software. Code quality seems to  
have decline rather than improve.

As far as the extensions. I understand if the code in them was a 
security hazard, i can see why they would not be wanted to be included 
in the default compiles. And as well, some with broken code, with 
features duplicated elsewhere and with not many apps which use them, it 
may not be a good investment of time to try to fix them, considering 
there is more valuable uses of time resources.
