Phase stereo is not currently implemented in reference encoder due to complexity, but will be re-added again later on.

With regards to Vorbis of course and, if it's relevant, aoTuVb5..

Can anyone confirm for me at which frequency Point Stereo begins to be used at Quality 0 ?
Is it just a predefined limit beyond which PS is used, or is it dynamically altered during encoding ?

And also, is the Hydrogen Audio Wiki on channel coupling correct in its statement that:

It's dynamically altered during encoding depending upon what -q value you use it mostly effect higher frequencies though. No Phase Stereo is not implemented the AoTuVb5 tunings only effect Noise Normalization and Point Stereo
