or simply
     
    ns <- getNamespace("MASS") ; unloadNamespace(ns)

yes, indeed.   That's a bug.

which seems to have been the main use, and the only one  used
in any R package on CRAN or Bioconductor, or else we would have

This is from the change,

  unloadNamespace() no longer loads & unloads an unloaded namespace - fixing
