Better dependable fields

[puzzledmonkey]

Dependable fields are a great addition to Nova and unlock some really powerful editing capabilities. However, the way it currently works, a large number of requests are sent whenever an object is changed that has several fields depending on it. For example:

Select::make('Source')->options(config('sources'))->displayUsingLabels(),
Number::make('Limit per order')->hide()->dependsOn(['source'], function (Number $field, NovaRequest $request, FormData $formData) {
    if ($formData->source == 'shop') {
        $field->show();
    } else {
        $field->hide();
    }
}),
Boolean::make('Show stock level')->hide()->dependsOn(['source'], function (Boolean $field, NovaRequest $request, FormData $formData) {
    if ($formData->source == 'shop') {
        $field->show();
    } else {
        $field->hide();
    }
}),
...

In this (simplified) case, changing the Source field will send 2 requests - one for each dependent field.

Would it be possible to turn this on its head, so only a single request is sent when the Source field (in this case) is updated, and the server will collate all fields which are dependent on the field and return an array. If - in turn - any of these then trigger other dependable fields, this will need to trigger another (one or more) request/s to the server - there's no real way around that. But in the case where we have 10 or 15 fields all depending on a single field, this would dramatically reduce the time taken to update the form and provide a better UX.
