I doubt very much that it is held by the majority of Protestant Christian Philosophers, although it is held by a few.

1 - "Among philosophical theologians based in the philosophy departments of Anglophone universities, Molinism may well be the most popular of five or six competing theories. For some defenses of Molinism, see Alvin Plantinga, “Replies to my Colleagues”, Alvin Plantinga, ed. by James E. Tomberlin and Peter van Inwagen (Dordrecht: D. Reidel, 1985), 313-396; Jonathan Kvanvig The Possibility of an All-Knowing God (New York: St. Martin’s Press, 1986); Richard Otte, “A Defense of Middle Knowledge”, International Journal Philosophy of Religion 21 (1987): 161-69; Alfred J. Freddoso, “Introduction”, in Luis de Molina: On Divine Foreknowledge (Part IV of the Concordia), trans. by Freddoso (Ithaca and London: Cornell University Press, 1988), 1-81; Edward Wierenga, The Nature of God (Ithaca and London: Cornell University Press, 1989); and Thomas Flint, Divine Providence: The Molinist Account (Ithaca and London: Cornell University Press, 1998)."
William Lane Craig has also made this claim in his debate with Helm on Justin Brierley's program "Unbelievable" last year.
