Don't misunderstand, I don't want to be a stick in the mud, but if it can't be quantized, it isn't very useful as far as science goes.
For example, if this UTF has a field nature, it should also have a particle nature too, which is used to transmit the effect. For it to be a useful theory, it needs to answer questions like: What is the particle's mass, what is the range of this new force, what is the speed of propagation, and so on and so forth.
