VAR and offside. It's such a simple solution.

[Eric the Half a Bee]

I'm with you for your first couple of paragraphs, I'm sure most sports do that and if there isn't a clear reason to overturn the original decision then they don't. Football talks about doing this but can't help itself. It messes things up then tinkers with the rules to try and stop that mess happening again but this just creates a new mess and so on.

That's the problem with your third paragraph. Create a three inch margin of error then VAR will spend five minutes trying to work out whether the offside occurred inside or outside the three inches. Just moving the line won't solve any of the VAR issues as a number of posters on here are patiently trying to point out.

The decision about body parts has been made, it's in the laws of the game and Forest Green Bluebird helpfully put it in the Palace v Leeds thread.

Yes, good points. There was me thinking I had a solution!
