So the answer is just to use only the weaker option forever?

No? There's a very specific technical problem that makes DNSSEC hard to deploy effectively. You can't just define it away. You have to pursue solutions that solve that problem. There's a whole huge solution space to draw from, but people are so path-dependent and so predisposed to like the IETF that DNSSEC is just the only discussion we seem to be able to have.

Fortunately, the WebPKI has been ratcheting (slowly) up security over the last 15 years, so when nothing else happens, which is what I predict, at least we'll be in a better place a decade from now.
