Arsene's idea doesn't solve anything. It's just 'change' for the sake of it. From an AR's perspective, it's easier to see a part of the body that protrudes into an offside position than it is to see a part of the body that will likely be hidden from view (to keep the player onside)
There's a trend of too much change over the last decade and that change is always done at excessive pace without the implications being properly thought through and trialled. It smacks of too many voices sat round a table with too many bright ideas purely to justify salaries and status. I'm not against change, but there's too much of it happening apace across the game and much of it seems pointless and therefore detrimental
Take the 'sledgehammer' approach to County Promotions for example. I understand some of the motivation, but they've gone too far in one hit. And the new model would be near-on impossible to reverse if it further damages the standard of refereeing, in particular leaving candidates ill-prepared for 5-to-4
And of course VAR. Probably the biggest revolution to the dynamic of the game ever
All happened overnight... almost in the blink of an eye in the wider context. The handbrake turn of VAR is probably it's biggest failing. No thought to gradual adoption of massive change
But I figured we get on well enough that I could call you anything without being dismissed OFFINABUS
