Interesting. So far I thought xlib and xcb are completely independent, but it seems at least on Ubuntu that the old xlib was replaced by an xlib wrapper on top of xcb (XLibXcb)? Did I get that right? That would be the reason then why e.g. libXext has a dependency to libxcb on my Ubuntu 11.10.

Anyway, depending on xcb.1.so isn't that bad, AFAICT. Where things are incompatible even between recent Linux distributions are some of the extensions (xcb-icccm, xcb-utils ...)
