Yeah, but in a parallel time-line, there can be plenty of things common to both timelines. So, references to things in The Defenders Saga doesn't necessarily mean the same time-line.
The proof will be either Feige speaking up, OR, in the D+ series, there is a reference to something that contradicts The Defenders Saga, OR, there are tons of references where everything is exactly the same.
In Hawkeye, tho, Kingpin seemed decidedly different dressed in white, no Vanessa, and running his criminal enterprise down on the street instead of some penthouse. Not to mention that he seemed powered up and not just very strong.
