We point out that the nonempty $R_h=ct$ cosmological model has some known

antecedents in the literature. Some of those eternal coasting models are

published even before the discovery of the accelerated expansion of the

universe and were shown to have none of the commonly discussed cosmological

problems and also that $H_0t_0=1$. The $R_h=ct$ model is only the special

(flat) case of the eternal coasting model. An additional feature in the

coasting model is that $Omega_m/Omega_{dark ; energy}$ = some constant of

the order of unity, so that also the cosmic coincidence problem is avoided.
