didn't you guess I was the culprit ?  :-)
I think I mainly mentioned MASS because it's been a standard R
package for a long time.

Probably not much, but
simple  M-estimate for regression with flexible choice of
psi/rho function is something not available as "high-level"
in robustbase::lmrob() nor robust::lmRob() I think.

E.g. if you have only categorical predictors, such "simple" M estimates 
may make much sense, no?
