I tend to agree. Although at the moment the phylogenetic bracket for feathers
(including 'protofeathers') is limited to Coelurosauria, or one of its

"BCF" is a crock (tree-dwelling sauropods, flying tyrannosaurs, etc), but the
idea of Late Triassic theropods such as _Coelophysis_ being feathered is much
more plausible. Further, the idea that basal neotheropods (or theropods)
possessed a feather-like body covering is a testable phylogenetic hypothesis;
BCF is not (at least not in its current form).
