Regarding the perpetuation of the Reformation (nor “reformatters,” which would be a clean install) being men like Charles Taze Russel, Ellen G White, Joseph Smith Jr etc.,
As you know, no. Such cults like cannot be said to be operating according to the primary tenet (SS) which defined historic Protestantism, as rather than actually practicing the supremacy of Scripture (which requires a more difficult quality of unity, by “manifestation of the truth” - 2Cor. 4:2), they are following Rome in effectively making a person or office elite superior doctrinal authority over the Scriptures, and like Rome, they require implicit trust in them (and boast of that manner of cultic unity).
While they hold to some Scripturally substantiated truths, they deny others, and like Rome, they add teachings which they wrest out of a few texts but which really depend upon their elitist claim to be uniquely correct interpreters.
“The Vicar of Christ is the Vicar of God; to us the voice of the Pope is the voice of God.
“Absolute, immediate, and unfaltering submission to the teaching of God’s Church on matters of faith and morals-——this is what all must give..”
This, too, is why Catholics would never dream of calling in question the utterance of a priest in expounding Christian doctrine according to the teaching of the Church;”
“He is as sure of a truth when declared by the Catholic Church as he would be if he saw Jesus Christ standing before him and heard Him declaring it with His Own Divine lips.”
“He willingly submits his judgment on questions the most momentous that can occupy the mind of man-——questions of religion-——to an authority located in Rome.”
“So if God [via Rome] declares that the Blessed Virgin was conceived Immaculate, or that there is a Purgatory, or that the Holy Eucharist is the real Body and Blood of Jesus Christ, shall we say, “I am not sure about that. I must examine it for myself; I must see whether it is true, whether it is Scriptural?”

“The intolerance of the Church toward error, the natural position of one who is the custodian of truth, her only reasonable attitude makes her forbid her children to read or to listen to heretical controversy, or to endeavor to discover religious truths by examining both sides of the question.” “The reason of this stand of his is that, for him, there can be no two sides to a question which for him is settled; for him, there is no seeking after the truth: - John H. Stapleton, Explanation of Catholic Morals, Chapter xxiii. the consistent believer (1904); Nihil Obstat. Remy Lafort, Censor Librorum. Imprimatur, John M. Farley, Archbishop of New York )
We furthermore forbid any lay person to engage in dispute, either private or public, concerning the Catholic Faith. Whosoever shall act contrary to this decree, let him be bound in the fetters of excommunication. — Pope Alexander IV (1254-1261) in “Sextus Decretalium”, Lib. V, c. ii: [considered abrogated by later canon law]
