I most certainly would include Calvin, Luther and Zwingli, probably more as developers of ancient heresies, and somewhat less as inventors of new ones.
But let us go back to the first millennium:
Simon Magus (the development of “Christian” Gnosticism)
Manichaeus (Manichaenism ensnared Saint Augustine for 9 years)
Ammonius Saccas (neo Platonism)
Montanus
Paul of Samosata (Monarchianism)
Sabellius (Modal Monarchianism)
Arius
Nestorius
Elipandus of Toledo (Adoptionism)
to name a few.

You would, but I don’t. Everything the believed they backed up with scripture. I cannot say the same with the Catholic Church.
What do you do when the Catholic Church and the Bible do not agree? WHat do you do when Tradition and the Bible do not agree?
