Yeah I don't see the PGA instituting different rules for better/worse players should LIV fail. Plus I think the idea understates how much of a betrayal LIV is seen as. I'd assume the bans would be a certain number of years after that last LIV event played, then you start over with no status.
I'm not really opposed to essentially splitting the PGA into two tiers. First, with the huge increase in prize money you're not just cutting up the same pie differently, you can support two events. And if you go to smaller elite no-cut fields for more elevated events, then there are more players for the backup event. I doubt they have the mix right as far as number of smaller events and number of players, but it's probably a step in the right direction.
The one thing I'd really love to see - continued expansion on the technology/coverage front. For the few minutes I could stand watching a LIV event, it was so comical that they talked up all these new mic'd up moments and awesome new access when the video quality is crap, the weird permanent banner down the side of the screen made it look like a web cam, etc. Give me 4k streaming, keep going with the mic'd up walks they've been doing but expand them to more players and caddies, give me condensed versions of each individual player's round on watchESPN, etc. And please for the love of God get rid of the "playing through" garbage.
