Well said, except that 0-conf was never viable; and thats not a blocksize issue.

I agree that 0-confirmation transactions were never really secure. However,
many operators had a business model that was based on 0-conf transactions
(e.g. the now defunct betting site Directbet). Therefore something seems
to have changed, because otherwise these operators would still be able
to use 0-conf transactions.
I can´t imagine that this is only due to increased fraud by people attempting to double-spend
a gambling transaction (e.g. double-spend after their bet already lost on Directbet). There has
to be a technical explanation why 0-conf transactions are not widely used anymore
when that was still the case in 2014-2015 (at least at Bitcoin gambling sites).
Satoshi said that 0 confirmation transactions were never to rely upon, or at least he literally considered 0 confirmation users as "second class citizens" in the bitcoin network:
It's not clear to me if he had 0 confirmations to be part of the network model. Big blockers often argue that 0 confirmations are perfectly fine and the only reason they aren't now is due the blocks not being big enough. 0 confirmations never made any sense to me. Maybe for smaller transactions, but I would rather trust an LN channel than a 0 confirmation transaction.
