I'm positive towards a change like this because I think current technology makes for some absolutely absurd offside rulings where a players nose, toe, or finger puts them offside in an otherwise perfectly executed run.
I feel the spirit of the offside rule is clear: You shouldn't be able to just run in behind the defenders and wait to receive the ball. With a rule change like this, we're moving from "anything even slightly offside is offside" to "offside is when you are passed the defender before the ball is released", which aligns much better with the intent behind the rule.
Also, I think it's a lot easier to accept a situation where you opponent scores a goal because of a perfectly executed run that was just onside, vs. having a goal you scored annulled because your nose was offside. A change like this will move the "just barely" situation such that an offside player will never be "just barely offside", and I think it will feel more fair to receive an offside ruling against you when the player is actually completely passed the defender.
