Not my approach, I tend to think more in terms of filter efficiency, but to each their own. One thing to know is the abundant filter and media capacity doesn't add to your beneficial bacteria, which balances with available nutrients, not according how many filters you have. In other words, more filters doesn't mean extra beneficial bacteria, a similar volume of bacteria will simply be distributed less densely. Beyond merely maintaining beneficial bacteria, some 'extra' filter capacity might keep your water clearer-- but there's still a point of redundancy.
I wouldn't do it for types of fish that prefer slower water. On the other hand, if you're planning for a future tank, it's one way to get a filter started, or partially started, for the new tank.
