Disclosure: I wrote the linked post.
The "gave it my Gmail password" problem has a better answer than "don't do that." Security kicks itself out of the room when it only says no. Reserve the no for the worst days. The rest of the time, ship a better way.
That's why I built the platform to make credential leaks hard. It takes more than a single prompt. The credential vault is encrypted. Typed secret wrappers prevent accidental logging and serialization. Per-channel process isolation means a compromise in one adapter does not hand an attacker live sessions in the others.
"Don't do that" fails even for users trying their hardest. Good engineering makes mistakes hard and the right answer easy. Architecture carries the weight so the user does not have to.
On the trifecta being "sorta-kinda solved" by newer models, no. Model mitigations are a layer, not a substitute. Prompt injection has the shape of a confused-deputy problem and the answer to confused deputies has always been capabilities and isolation, not asking the already confused deputy to try harder.
You want the injection to fail EVEN when the model does not catch it.
