The best practice would be not to use arrays.. *duck*
SCNR, and sometimes arrays do make a lot of sense of course.

Not out of the box, but of course you could create a 
Form\ArrayfieldViewHelper.
But probably you won't even need that - If I got you right, this is what 
you need:

But be aware: By tweaking the POST data one can add arbitrary keys to 
the array so you should sanitize it on the server-side.
