Proposal

The sate "hover" would not have to generate default value

Motivation and context

The sate hover would not have to generate a defaut state as it works at this moment.
Right now, this option is unusable in many case
Example :

"bghover": (
      property: background-color,
      class:bgh,
      state: hover,
      values: (
          primary:$primary,
      ),

---

.bgh-primary {
  background-color: #25bbe4 !important;
}

.bgh-primary-hover:hover {
  background-color: #25bbe4 !important;
}
