This is addressed in the paper's Preemptive Rebuttals section (Concern 9: "The Proofs Are Trivial").
At 2k lines of lean, the criticism was "these proofs are trivial." At 9k lines of lean with 541 theorems, the criticism is... still "trivial"? At what point does the objection become "I didn't read it"?
The rfl proofs are scaffolding. The substantive proofs (rust_lacks_introspection, Inconsistency.lean, Coherence.lean) are hundreds of lines of actual reasoning. This is in the paper.
