Yes. I don't see a single one of those comments implying that Rust developers didn't know about proper abstraction in 2016.

The closest might be kaoD, who says:

i.e. proper abstraction was not their priority at that time.

I think you are reading into these comments and finding meaning that doesn't exist.

So you agree they weren’t saying anything that substantively refuted my claim that proper use of abstraction was a reasonable expectation to have of Rust devs in 2016? Then what exactly are you disagreeing with?

Edit: So, yes, I agree that Rust devs knew about a abstraction. When the replies tell me that, they’re not disagreeing with anything I’ve said. My point is that it therefore follows that it was a reasonable expectation to have of the code, that it obeys abstraction. They were giving excuses for why it might not have kept up with eg newly discovered bugs, but not why it would fail to get such basic stuff right … besides, of course, it being the dark ages of 2016.
