Description
Was this unfolding database meant to be used in simplify_dep_elim? Because it doesn't seem to be used anywhere in this file, which is a shame. I keep having to call autounfold with dep_elim; simpl_eqs (or simplify_eqs/simplify_dep_elim) in order to get any mileage out of these tactics (eq_rect_r comes up in even the simplest of instances). Would there be a cost to including it in the tactics?

Research direction
Start with theories/Program/Equality.v at the linked lines and inspect simplify_dep_elim, along with the related simpl_eqs and simplify_eqs tactics. Determine whether the dep_elim unfolding database can be included without unacceptable cost, then verify that the basic cases involving eq_rect_r work without a separate autounfold with dep_elim step.
