I meant the spec should do this, not your browser

This isn't required by the X3D spec.  It's much easier to implement 1
wrapper then hundreds of concrete classes.

The instanceof checks would always be browser specific which we want to
avoid.  SAI code should be portable between browsers.  There are some
concrete interfaces on the higher levels of SAI but we haven't implemented
them yet.
