Thanks for your feedback. In my case, Bob the manager said this would "make backups easier" xD
The general pro that I see is "transactional". While I can understand that, it's irrelevant in our case: users upload files through AJAX, that happens **before** they submit the form. That means, the file gets saved in an HTTP exchange that happens **before** the actual data insertion transaction.
As such, be careful too that this argument does not be irrelevant in your case like it is in mine.
