Absolutely agree. Part of the problem here is not just having the knowledge required to avoid such pitfalls, but also having enough knowledge to realize that you don't possess such knowledge. We see time and again plenty of newbies on this forum who think that unplugging their Ethernet cable or turning off their WiFi means they can do whatever they like on their computer in complete safety. If you don't have the knowledge to safely create an airgapped wallet, the danger is you don't have the knowledge to realize that either. Perhaps Andreas' method of just saying "Never use a paper wallet" isn't so bad after all, rather than saying only use one if you can do x, y, and z, and newbies thinking they know how to do that. If you say "Never use a paper wallet" then this applies to the vast majority of users, and the few who know how to do so safely will also know they can safely ignore such statements.

But at the same time we should be steering newbies away from risky solutions such as creating their own paper wallets or using custodial closed source web wallets.

I fail to see a single benefit of doing this over writing down a seed phrase. You first have to generate the seed phrase anyway, you are trusting additional hardware and software to generate the QR code, it is time consuming, the potential for making an error is huge in comparison to a seed phrase, it is incredibly difficult (if not impossible?) to use a metal plate if you prefer that over paper, it is time consuming and error prone to duplicate, and trying to figure out/brute force a mistake will be exponentially harder than doing the same for a seed phrase. What is the use case here?
