I feel like that would have happened by now if it was going to happen ever, but maybe Im missing something about why its different this time
Sealed Deck is a little different from normal deck building
This is the list I used to win the 2002 Vintage Championship: Creatures (8) Lands (9) Spells (43) Yeah, thats right, Library of Alexandria and just eight other lands
Pair that with Duskmourns The Swarmweaver, which also has a delirium ability to give Insects and Spiders +1/+1 and deathtouch, and delirium quickly becomes a great tool in creepy-crawly decks.
The option to run a Partner Commander is also a big positive, as is the wonderful thematic storytelling that went into its design
I dont have anything against Earthcraft in a 75% deck, mind you, and this is a great complement or replacement, depending on how you build
