What's wrong with the present EDID parser in X.Org?
It wouldn't be a problem to move it into a separate library which
is used by both the server and libXrandr.
I't code that has been well tested (including the code that generates
modes and handles quirks).
Replacing it doesn't seem to be warrented as the existing code
already provides a single entry point.
