  It was recently argued that f(T) gravity could inherit "remnant symmetry"
from the full Lorentz group, despite the fact that the theory is not locally
Lorentz invariant. Confusion has arisen regarding the implication of this
result for the previous works, which established that f(T) gravity is
pathological due to superluminal propagation, local acausality, and non-unique
time evolution. We clarify that the existence of the "remnant group" does not
rid the theory of these various problems, but instead strongly supports it.
