Well that would certainly add consistency, but what about the times when it's blasted at someone's hand point-blank or if a player purposely kicks/heads it onto someone's hand? There's always tricky situations like this that will arise, but back in the day if it hit your hand in the penalty area regardless of how it got there then it was a penalty.
I feel like consistency is the most important thing. If a player can purposely hit other player's hand with a ball then it can be counted as skill. At least you know what are the rules and there is no room for interpretation.
I actually played futsal (5 on 5) against one team and they insisted on those kind of rules. Their pitch was really narrow and when you stand in front of guy taking corner you are actually standing inside your penalty area. Then the guy just kicks the ball into you and tries to hit your hand. That kind of play works once and then you adapt.
As much as I hate that people will take advantage of it, kicking it directly into the hands of the opponent, but at least there is no more argument when it's consistent.
I agree with Trofo (I played for futsal than football in my latter years) and there, in most non-competitive matches, teams always ask for a handball however the intention or direction. I was a victim a lot, because they'd just kick it into me from a corner (I'm always guarding) and exactly that, I learnt to adapt. I had to even learn to ASK for handball because instinctively, I ignore unintentional handball.
I personally don't like it, but then there's no more argument, and then people can adapt, punish more severely intentional handballs, or at least, count unintentional ones as indirect freekicks in the penalty box. Still better than maybe-handball, maybe-not.
Anyway, definitely not a good day for VAR yesterday in City's match. I know offside resets after defender controls ball, but no VAR intervention (just referee decision)... and supporters and referees in general don't allow an offside attacker to intervene with play later. I feel like it gives you an advantage. You're coming from behind the defender, who psychologically thinks you're offside anyway... but yeah I would forgive all that if Villa also would have their penalty given for handball.
