Here’s my solution until this is fixed in vue:

function dedupeModelListeners (data: VNodeData): void {
  if (data.model && data.on && data.on.input) {
    if (Array.isArray(data.on.input)) {
      const i = data.on.input.indexOf(data.model.callback)
      if (i > -1) data.on.input.splice(i, 1)
    } else {
      delete data.on.input
    }
  }
}

Turns out someone was relying on data.model.expression, but I can’t find a way to allow that without breaking a bunch of other shit: https://github.com/vuetifyjs/vuetify/issues/4460#issuecomment-406870878
