Backpass rule probably did at first, I mean I remember TRFC losing a friendly 7-1 to Liverpool because one of our CBs forgot the rule had been brought in and kept passing it back in dodgy situations. That was literally the summer it was brought in though.
These days it's kind of immaterial because even hack keepers in non-league are trained from a young age to use their feet. Eric Nixon was arguably one of the best shotstoppers in the country at his peak for us, but couldn't kick the ball in a straight line. This was an issue as the game evolved even before the passback rule, but afterwards pretty much made us his ceiling.
I remember a game a couple of years ago where a dodgy backpass was played to our keeper, and it was aerial. He panicked and headed the ball, conceded possession, they scored. A 90s keeper, even post-rule change, is collecting that ball in his hands every time, the same way defenders make tactical fouls. But it's so ingrained in them not to do it that it's not even like a rule but just something you don't do. So maybe it's not immaterial but you don't see many goals arise from it, to my mind.
