Yes. Sometimes, it can be useful. Here's an example:

Let's say we have in our db "date_and_time_field".

In Razor View, we want to use two form fields. The first one "Date" (maybe with jQuery UI Datepicker). The second one "Hour".

In the Controller Action, we compose the "date_and_time_field" by means of Request.Form["Date"] and Request.Form["Hour"].

There are other scenarios where it can be useful:

• A cross-table (with checkBoxes in Razor view)

• The collection Request.Unvalidated().Form (maybe this is not part of your question: I don't wanna be off-topic)
