Euler angles are not used in any Modeller interface; it's all rotation matrices or rotation about an axis. The only place to my knowledge that Euler angles are used at all in Modeller is internally for CG and QN optimizations. For any exposed interface I agree that quaternions are probably the best solution.

P.S. As regards putting this stuff in the IMP kernel, that wouldn't work if you need to use any of the decorators, since those are defined in the core module.
