Sure, but here's how I see it:

1. You don't need one. It's not like this is a matter of replacing something either, you just straight up can run a beautiful, healthy tank fuge free.

2. When you do have one, there are diminishing returns on its usefulness as a filter compared to just doing water changes and having good flow/skimmer.

3. They collect detritus over time. This is just more maintenance.

4. They take up resources (space, electricity, money, etc).

Given that I can run two tanks side by side, fuge/no fuge and end up with more or less the same results after a year, I'm of the motivation that they are completely dispensable.
