Here for rides.
If the referee is so minded he could give a penalty at every scrum. And every lineout. And 80% of rucks, and 60% of mauls. And at about 1/3rd of tackles. So be careful what you wish for.Nobody has EVER scrummaged legally.... It's just slightly more blatant nowadays.
But, and this is the killer, most players don't realise that 90% of their cheating at scrum, lineout, ruck and maul is utterly ineffective, as, for the most part, they are as bad at cheating as other skills! Therefore it is completely pointless, it changes not a thing and thus, totally immaterial. So the ref, wanting to give 30 blokes a game, and, at elite level, knowing the audience hasn't turned up or tuned in to hear him play tunes on his whistle, notes the cheating, ignores some of it with a rue smile and a weary head shake, "manages" most of it, and only pings the material offences and the most egregious cheating that he/she spots.
