The changelog says indeed:

Deprecate method Request::get(), use properties ->attributes, query or request directly instead

We could change the get called with input maybe as well..? I like to consider fixing in the correct way.

What do you mean with input?

The problem is that at some locations our API is not clearly stating if the expected parameters should be in the query, body, ... . So migrating away from get(), which checks all possible sources, might be hard.

What do you mean with input?

see: laravel/framework#57962 (comment) :)

But that might only works with Laravel too bad :(

But yea, I get your point, we now need to migrate to, which isn't always easy to know what to pick from the code:

    // use this if the value comes from route placeholders or custom attributes
    $value = $request->attributes->get('some_key');

    // use this for GET query parameters
    $value = $request->query->get('some_key');

    // use this for POST-submitted data
    $value = $request->request->get('some_key');

But that might only works with Laravel too bad :(

Yep, there is no input function in Symfonys request.
