   But the same impedance loads the collector and reduces the gain.
   Ideally, the two effects should cancel.

Yes, except that in a phase shifter (such as the Magnatone or the Univibe)
the top and bottom loads are different.

(I suppose a spice simulation would be the right thing about now.  :-))
