It will make manipulation by the MM's much more difficult, especially if you have level 2.
For example a way of lowering the PPS is to put 5 shares on the bid but 5 million shares on the Ask. If you hit the bid, your order will likely not be filled but you will create a lower ASK. This lowers the PPS and is a manipulative practice. Such manipulation will be more obvious starting now.
There are hundreds of ways MM steal money from the public and this license to steal needs to be stopped and this is just one more thing that will get in these criminals way and help the honest investor in their investment decisions.
