Everything you read is partially wrong.

Xinerama consisted of a low level protocol for carving up the root window
into screens, and a high level multiple monitor protocol.
The high level support was removed in favor of XRandR.
ALL existing multiple monitor support, except for "zaphod mode" which you
almost certainly do not want, absolutely requires the low level Xinerama
component. This includes but is not limited to XRandR, which xmonad uses
for multiple monitor support. It still lives in libXinerama, all the API
calls are named for it, etc. It causes remarkable amounts of confusion.
