Yes, Robin Hanson does, but his theory is a collapse theory so don’t hold it against MWI.
ETA: actually, no, I do not agree that Robin Hanson does counting.
If I google “mangled worlds”, I am told: “Describes a variation on the many worlds interpretation in which the Born probability rule can be derived via finite world counting.”
I reached the opposite conclusion from that page.
