Really, Nikon, Canon, etc. do not change their raw formats with every camera, so a raw processor that reads the headers properly can decode all the data. There's a difference between just "reading" something and really understanding it, though. The best raw processing programs lag behind the camera releases because they typically use parameters measured from actual cameras for noise processing, anti-aliasing, color processing, sharpening radii, etc.

You can't get around that, unless you want the sensor to not change between new cameras.

It is not only basic sensor layout needed to know for sucsessfull RAW processing (Basically enough for rough conversion).

From camera to camera changes color filter array and correspondingly preamplifier voltages, so colors may change not dramatically but unpredictable. There is a reason for new RAW for every camera.

For about 2003-2006 were RAW converter utilities with possibility to choose sensor color layout (RGGB, GRGB, CMYW etc.) and amplified meanings of each color. Interestingly but not for serious photo work. (The purpose was to catch RAW data from cameras normally not writing RAW, only JPEG).

Another reason is color management with complex color profiles for every camera. Without it, reading only data you'll get gray skintones or violet skies.

What is so different about each camera type of raw file that makes them disimilar and why can't they all be the same or at least compatible?

They are "at least compatible" so your question is meaningless.
