Recently, the release of Chains of Asmodeus bring a sequel to Descent to Avernus, making it a full campain to 20. How would you see "official" DMsGuild by Wotc sequels to campaign sold like these? Think, a sequel to 20 for Curse of Strahd, Tomb of Annihilation, Storm King's Thunder and so on. Available as PDF, then as POD if successful enough, no need to print with risk of making too many books, and finally high-level support. They can also be used to promote old adventures, that are still sold.
Is this a bad idea?
