I agree with you. But what about files it works on, heavily, then decides they can't be defragged further? then it tries to defrag them again and again and again. And that's the end of my story.

No, I don't - if you want files not to be defragmented, then you
have to set the flags yourself in some way. You have a specific need
that can be solved by some scripting to describe your defrag/no
defrag policy. xfs_fsr has no place is setting defrag policy; it's
function is simply to find and defrag files.
