With you removing that gauze, your fuel pump filter is also now your fpr filter too lol!

It was more of a rhetorical question.
What I was getting at is how likely is it that these FPR's will have a problem from the tiny amounts of debris? My guess is none.
I'd bet any debris from the fuel rail will pass straight through the FPR and back to the tank like you said. The amount of debris is so small to be of no consequence in the tank sloshing around because firstly, the gauze on the pump is huge by comparison, and secondly, they are self cleaning to a point as the debris is in constant motion.
I've seen FPR's in for hundreds of thousands of k's with bugger all debris anyhow.
