Qualchouse will be providing the fungi drivers and although potentially functional for a few decades, after 2-3 years your buildings existence will stop being supported by the upgraded city. Neighbors will force you to upgrade because even though the pesticides for the new fungi eating microorganism are compatible in principle they are only provided in a container designed for the new buildings' sprinkler systems. The "open-the-container" and the "create-open-pesticide" communities soon discover that competing is a thankless multimillion costs job after producing nothing. Eventually after an upgrade the lucky ones who got unlocked on the outside end up forming militia to take control of the nearby caves. Humanity will have thus realized the early 19th century dream of a pastoral life.
