Ratzinger's belief of “tradition” included “the living process whereby the Holy Spirit introduces us to the fullness of truth and teaches us how to understand what previously we could still not grasp (cf. Jn 16:12-13), then subsequent “remembering” (cf. Jn 16:4, for instance) can come to recognize what it has not caught sight of previously and was already handed down in the original Word.”

You say, “ What Ratzinger has written supports the position non-Roman Catholics have taken in that Rome has created the various dogmas they believe which are not found in nor grounded in Scripture.

Attempting to cite John 16:4 for support of this "subsequent" remembering allows for a hole big enough to drive the solar system through and allow Rome to continue to develop pretty much any dogma desired.

What part of “already handed down in the original Word” has a hole big enough to drive the solar system through?

It’s his redefining “tradition” that is the hole behind enough to drive the solar system through. His definition allows pretty much whatever Rome wants to claim it’s now “remembered”. The proposed Fifth Marian dogma comes to mind as an example.
