Samsung/Android/Google Pay/Wallet thing never gained traction despite having access to the chip is exactly what we’ll see if the chip just get opened up free for all.

You realise that in the UK and a lot of other countries people mainly pay by contactless and while you can do that with just your bank card, many link it to Google/Apple pay in their phone? The Amex UK app used to offer their own implementation as well for contactless payment, but they also supported Google pay/wallet so eventually decided to drop their Amex app implementation of contactless payments and just told people to use Google pay. Don't equate them not gaining traction in your country with that being the case in general, especially if you're from the US, where banking technology seems to be 15-20 years behind a lot of the time.
