In Bitcoin Cash no one really waits for confirmations for small amounts outside of exchanges. This becomes a reliable method of transacting because of the same reasons Satoshi outlined in the historical snack machine thread.
The reason it stopped being used entirely on Bitcoin SL "Core" was due to the radically inconsistent fees, which were caused by artificially restricting blocksize. This was considered good because it would instead lead to much higher fees, make the original chain into a "settlement layer" and push ordinary users off the chain and onto "2nd layers" such as the Lighting Network.
