Is it good practice to use forms solely for binding and validation purposes?

Question

symfony

Hello.
Actually the question is, is it good practice to use the form component solely for data binding to the model and for validation? For me, these seem convenient when compared with the use of "manual" data binding in the controller, for example, when there are continuous checks for the presence of a key in the array of values , or the same checks, but in the service. if(isset($data['key'])){do_some_code();}

If you use something like Backbone on the client, for example, then https://github.com/schmittjoh/JMSSerializerBundle is a good fit, since you don't have to do anything "by hand", everything just runs in json format. For validation there is symfony.com/doc/current/book/validation.html
