Primary constraint analysis of Newer General Relativity recovers five tensor and three vector constraints and identifies a previously unreported scalar-sector degeneracy that produces one or two constraints depending on the c_i values.
f(Q) gravity exhibits pathological behavior in its scalar-tensor representation.
