(In reply to comment #2)
> The spec now says:
> "The transform functions ‘matrix’, ‘rotate3d’, ‘matrix3d’ and ‘perspective’
> get converted into 4x4 matrices first and interpolated as defined in section
> Interpolation of Matrices afterwards."
> 
> In WebKit, for rotate3d(), we will blend single-axis functions without
> creating a matrix and decomposing. I think this makes most sense. I think it
> would also make sense to allow rotate3d(0, 0, 1, ...) to blend with
> rotate(), rotate3d(1, 0, 0, ...) with rotateX() etc.

This is fixed in the latest update of the specification text and resolved by
the CSS WG.
