An appointment to be welcomed, but with a word of caution. HW will have to work within the confines set by the PGMOLs "Stakeholders" - The Premier League, the Football League and the FA. These are the bodies paying the piper, so they get to call the tune.
HW may well find that he is operating within more of a straight-jacket than was the case with his current, and previous, employers.
I sincerely hope he has the courage and the "licence" allow his referees to officiate the games without fear or favour and attack some of the cancerous elements we see weekly. The game will be a better spectacle for it.
