// processModelsMappedFromFormRequest() was done quickly over morning coffee, may be unintentional psuedocode...

// Later... dawned on me that return new $model(array_combine(array_values($map), $data) limits it to 'create'
// rather than 'process'; perhaps updateOrCreate() instead of new, passing in an optional array of ids? That
// will have to wait for tomorrow's coffee, though...
