The loophole seems to be having an app pinned to the screen (I've never done this, but it presumably keeps the phone from locking) while requiring you to have an unlocked phone to use NFC payments. This doesn't seem to be a common scenario (I can imagine doing this in some sort of kiosk mode, or giving the phone to a kid and locking the app so he can't wander around).

This is why Samsung pay is king, the NFC only turns on when you’re using Samsung pay otherwise it stays off

Turn off NFC unless you are using it at that moment.
Woah, first I learned of this. https://www.lifewire.com/turn-off-nfc-to-secure-your-android-smartphone-2532822
Kinda sucks that there's no quick button for that. I can turn off Bluetooth, wireless, auto-rotate, etc in a single setting but not NFC?
Many Samsung devices have a quick button for NFC toggling in their drop down menu, not sure about other phones though.
You can try using Tasker to create a task that turns on NFC and launches Google Wallet / Pay afterwards.
After that, create another profile to turn off NFC when the screen is locked.
You can diasble all sensors and make a quick button for it in dev settings, dont remember how exactly it is called tho
