"Can you find "thousands and thousands" of judgments which look like your two cited dogmas?"

You're switching terms. You are now using the term judgments. But before, you specifically said infallible definition:

"Therefore Lumen Gentium §21 contains an infallible definition."

A dogmatic judgment of the Pope is an infallible definition, in the sense that Bp. Gasser is using it. He's responding to a proposal to require a formula for ex cathedra pronouncements.
