Does the v-b-hover directive provide a convenient way of passing not only true/false, but also a custom parameter? If you have multiple elements on your page, it can become quite tedious and resource intensive to create a large set of handlers.

For the time being, I resorted back to using the event hooks directly on all the elements, similar to as the directive: @mouseenter="onHover(0) @mouseleave="onUnhover(0) and so on (see also comments at end of #4771 for more use cases)
