Waste World had some cool charts, but nothing beyond what you had in Arduin and WFRP 1e.

If you survived a crit in WW, there was always bionics or bio-tech healing as possibilities.   However, much on the crit chart was "boom goes your life" options...which meant your friends would have to like you enough to scrape your bits in a bag and bring you back for a full body cloning or cyborging.

We never had a problem in WFRP with crits.  Few PCs ever survived a couple of rolls on the charts.

I think the main issue with these sort of crit charts isn't the question of just how violent they might be, but just how repetitive. If its TOO easy in a game for you to get the "your blow smashes open his skull like an over-ripe watermelon, brains splay out in a 90' arc for the next 2d20 feet" result, then you can end up repeating those words over and over again to the point that they don't even MEAN anything anymore!

If absolutely everyone dies a "totally awesome gruesome death" every time, you'd better be damn well sure that you've got at least a thousand different deaths for them, otherwise the impact of it will turn into tedium damn fucking quick.
