I recently met the following use case: create a FormData object from a 
<form />, send it to some listeners that can actually edit this 
FormData, to finally send it via a XHR to the server. Listeners can add 
some data (with FormData.append) but I would like them to be able to 
edit or remove data (for security concerns, or whatever else). The only 
solution I found is to create a new FormData-like object that mimics the 
real one but with the addition of some functions. In fact, I gently 
expose the “fields” object or array and transform it to a real FormData 
object when calling toString() or something like that.
By the way, some features are clearly missing on the FormData interface.

Best regards.
