Good point. You're right: > ac$ git grep -n sub.up_to_date_p > lib/Autom4te/FileUtils.pm:190:sub up_to_date_p ($@) in that removing it from automake should not impact any existing installation of autoconf. However, autoconf's lib/Autom4te hierarchy is sync'd from automake, so we would still need to make an adjustmake to autoconf before its next sync. So fine to remove from automake after all. Good!
