There were concerns that the mallet is pretty useless, and hard to make. The regular hammer should be able to do the functions a mallet can do, which is an easier implementation than removing the mallet physically.
You can find the thread here:

I do not know the functions of a mallet so please raise any issues you see with this suggestion. I am merely the messenger.
