It really does feel like they are setting that up, which honestly would make sense. Almost every D+ series in the near future and those that have already released are focusing on succession/complimenting characters of sorts. Billy will replace Wanda (eventually), Sam replaced Steve, Kate replaces Clint (likely holding the same mantle), She-Hulk replaces Hulk, Ms. Marvel either works with and/or eventually replaces Carol, etc.
Really these series are just extended cut origin stories for characters that we are going to see come into play in films, but at the end of the day, I keep going back to Feige's comment about not needing to see D+ shows to still follow the MCU and so far he's right. While things of consequence have happened, not much outside of a few costume changes cant be explained away in a sentence or two. Even Sylvie busting open the multiverse can be explained away in No Way Home. Because of that, I really can't see Hawkeye actually getting killed because that would take some major explaining, but alas we'll just have to wait and see.
