Right, and that's the part where I said "A genuine 90W type-C brick seems to only have..."

I should have been more clear, for sure.
Edit: I have done work in PD compliance and pre-certs. We're still in the wild west days of the PD/Type-C standard in general. If the type-C was a pretty new implementation (read: as first gen), then I've seen all sorts of weird things - an optional 12V "only" (implication being it supports all mandatory modes below that, as that's required) doesn't even phase me. Is it dumb? Yeah - but the ecosystem is just barely starting to understand how to not do things terribly.
I'm sure you've seen straight up bad things if you're doing PD related reviews :)
Edit 2: (Also for /u/Darrena) - You can pick up a PD voltmeter if you're interested to see WTF is going on: https://www.amazon.com/MakerHawk-Multimeter-Multi-function-Capacity-Detector/dp/B07GQLYMR9/ If it so happens that the 12V contract is being negotiated, then this will show it. The other thing I didn't mention is that if it's only negotiating 12V, it looks like the output is capped at 36W (12V*3A), however, since it's an optional contract, you can actually get away with going over - I'm really curious what is actually happening. If the input voltage for the DC Jack is already 19.5V, you'd think they'd just implement 20V...
