I can’t think of any team who has gone to a RWC with the intent of using injury replacements as a strategy for winning. Neither can I think of any injury replacements at a RWC that haven’t been considered genuine.
If you can provide previous examples of ‘sneaky replacement stuff’ happening that would be great.

There's a million of these. Backs replacing forwards and vice-versa.
It says injury of course but how do we know if they were injured? There's proof right there that teams replace players with not an actual like-for-like replacement but someone more suited to the squad.
The onus shouldn't be on me to show WR (World Rugby) don't do fuck all due diligence (because they can't really) in evaluating the merit of an injury replacement.
