So we have advice from the government or your HN comment to go on. There needs to be more substance to your claims

Asian countries have low SIDS despite infants commonly sleeping with their mothers.

To quote our pediatrician: "do you believe in UFOs? That's roughly in the same ballpark in terms of connection with reality".

This part of the reply to my SO's question about this. Later he explained that it's mainly drunk/high people who suffocate their children like that.

You only need a sufficiently wide bed and separate covers for the parents - that's it.

> mainly drunk/high people who suffocate their children like that.

That's a lot of people!

> You only need a sufficiently wide bed and separate covers for the parents

Why even take the risk.

If the combination of drinking and sleeping beside your infant leads to a higher chance of suffocating them you can ask people to stop drinking, stop sleeping beside their infant, or both. History has shown us that people won’t stop drinking so I think recommending the other potential solution makes sense.
