Not in any formal way, but when you suddenly have 0 pushback the mental question of was that right alleviates, and what follows soon after is you stop questioning your judgement and stop caring about even making a mistake.Umpires were never accountable to players during a match though? And while the players can't remonstrate the crowd will more than make up for it still if there's a howler.
Mark my words, this is going to get worse.
Fans just don't just count, because no umpire would ever feel like fans aren't just always screaming - it is background noise in the end.
