Thanks, CharlieHall, but my point was that even since R’ Shach said this plenty of people who consider him to have been the gadol hador go to Touro and elsewhere anyway. The idea that every pronouncement (whether documented or rumored) that a gadol hador says is to be followed, is simply not observed in practice. People tend to rely on more lenient opinions by other rabbis, as well as being influenced by the gadol hador.
Now that we’re listing, can someone list rabbis who approved of evolution or an ancient universe? That would be helpful.
