      Appears to be the result of the code in insert.cpp in userAllowedCreateNS

      Specifically 

       if (coll.find(".system.") != string::npos) {
// this matches old (2.4 and older) behavior, but I'm not sure its a good idea
        return Status(ErrorCodes::BadValue,
                      str::stream() << "cannot write to '" << db << "." << coll << "'");
}

      This conditional looks for .system. anywhere in a collection name.

      It appears to have caught a user supplied collection name of tmp.mr.system.users_1882
