No, by my logic, fans who demand stories that deliver "permanent change" in their superhero comics are asking for something that they've never had in the first place.
"Permanent change" just isn't a thing in superhero comics. The stories matter due to their execution, not because they made a change that couldn't be undone.
Kraven's Last Hunt isn't diminished because Kraven's climatic suicide ended up not being his final curtain call.
The death of Aunt May in ASM #400 is still powerful even though it ended up being a hoax.
And so on.
And continuity absolutely matters because stories continually build off of others to create a constantly unfolding tapestry.
