Networked root motion montage with rotation fighting smoothing

A licensee is reporting a sim proxy is playing a networked anim montage with root motion, that the rotation changes will fight between what's produced in ::SimulateRootMotion and ::SmoothClientPosition

There is a workaround by skipping smoothing when a networked RM montage is active, but I'm wondering if there's a less aggressive solution. Especially considering cases where: 
1) the montage is starting or ending (i.e. possible abrupt transitions between smoothing being active or not
2) sim proxy receives a replicated state during the middle of montage playback
