There is no easy way to reuse query arguments via url view helper or controller plugin. If current page has some query arguments (a view template doesn't know about them) and it's necessary to create url to this page, remove some query arguments or/and add some other arguments.

For example current page is /blog?sort=date&order=asc
It's necessary to create url /blog?sort=date&order=asc&page=2 - add argument page=2 and save other arguments, if they were.

$this->url(null, [], ['query' => ['page' => 2]], true); 
// returns '/blog?sort=date&order=asc&page=2'

$this->url(null, [], ['query' => ['page' => 2]], false); 
// returns '/blog?page=2'

Now current page is /blog?sort=date&order=asc&page=2
It's necessary to create url /blog?sort=date&order=asc - remove argument page and save other arguments, if they were.

$this->url(null, [], ['unset_query_params' => ['page']], true);
// returns '/blog?sort=date&order=asc'

To realize it I rewrote Url View Helper. But it isn't a good solution. I think it's necessary to go deeper, to Route.

So I would like to discuss this feature.

I wrote my own url helper that wraps oryginal helper and adds functionality to reuse query parameters. I need to inject request to get current query.

public function __invoke($route = null, $params = [], $options = [])
{
    $requestQuery     = $this->request->getQuery()->toArray();
    $optionsQuery     = isset($options['query']) ? $options['query'] : [];
    $options['query'] = \array_merge($requestQuery, $optionsQuery);

    return $this->view->url($route, $params, $options);
}

Couldn't for some reason this be done in oryginal helper?

Yes, on original helper. I don't see the need for separated helper for this case.
