I can definitely understanding wanting to wait and see what happens before moving AoS seasons 5 and 6 further back on this timeline. But it does really seem like the Marvel TV team is retconning the references to Infinity War in season 5 to keep Season 6 pre-snap--Jeph Loeb and Jed Whedon have been very consistent in this even if they're not sure how to address the timeline issues directly.
Honestly, given the disconnect between the film and TV branches of the MCU at this point, it seems kind of hard to believe that any of the current Marvel shows will include the Snap or the 5 year Snap Gap. If AoS can walk right up to the snap and then backtrack, there's really no reason for the smaller scale Runaways and Cloak and Dagger to try and write around it.
What we're probably looking at going forward is that only the Marvel Studios movies and Disney+ MCU shows set after Infinity Wars will acknowledge the Snap Gap. The three remaining MCU TV shows overseen by Jeph Loeb will continue running until they are cancelled, and will always be said to be set pre-Snap regardless of how much time passes in each show or how much they reflect the present day rather than 2016-2017. It'll be like how MASH ran for 11 years but the Korean War it was based on occurred over only 3 years. We'll probably see diminishing ties to the larger MCU in each series. (It's not like Runaways has that far to go.)
Upcoming shows like Ghost Rider and Helstrom probably won't be officially part of the MCU, they'll just be vague about whether they're tied in for the entire run of the series.
I'd love to be wrong, but it seems like that's just going to be the reality until Marvel sorts out whatever issues they're having that led to this silly rift in the first place. Given the Disney+ shows, it's not like they're opposed to working in ongoing small screen narratives into the MCU going forward, it's just internal politics effecting the continuity of the MCU as a whole.
