I agree that sedeprivationism makes the most sense, and it addresses many of the objections from both sides of the R&R vs. SV divide, so much so that the R&R Father Chazal independently formulated a thesis that was incredibly similar to sedeprivationism (although he denies it). I had hoped that Father Chazal's position might help heal the rift among Traditional Catholics, but both sides are extremely stubborn.
