I used to work for a company which later got bought by Fiserv (a large payments provider). I had these headaches re: transaction data. Wrote a lot of SQL to reconcile the pairwise sync problem. I tried to convince them that this is a problem for a blockchain, but I grew impatient and left.
So I'd say that it has caught on, just in a way that doesn't involve the users' preferences as much as I'd like. Because it's not like Fiserv is going to let their end users transact with any of the other assets on Solana. They'll wrap it in an interface that just calls it "$" and the user will be none the wiser.
Just a few weeks ago Fiserv launched a stablecoin on Solana: https://investors.fiserv.com/newsroom/detail/2848/fiserv-lau... I doubt they listened to me, probably just came to the conclusion independently.
