hmmmm....that is possible especially in very liberal dioceses. However, and I am speaking for myself, if I was denied advancement from the local bishop because I prefered to say the TLM over the Novous Ordo, I would take it up with the Vatican.
As would I. But it's better if real protections are built-into the promulgation to begin with, and then strictly enforced by Rome. Here in Boston, I've seen more than my share of priests get shafted for doing what is right, in this and other matters, in mild defiance of the bishop who is flouting canon law, rubrics or decorum, as the case may be. Appeals to Rome are notoriously slow, and the process is skewed in favor of the bishops in most cases. Putting teeth in the legislation would at least help those priests with the nerve to reserve a Sunday Mass in their parish for the Tridentine Rite.
