It is known that games are dominated by casuals. Wanna sell a lot of games...make them as easy as possible. Even Baldur's Gate 3, a much bigger game than 7 Days to Die with a much bigger modding community stated that 40% of their players use mods, and that was after the devs patched in official mod support, 4 years after the initial release of the game. Mod.io states: "Our case studies show that above 40% of players engage with mods when they’re accessible in-game, which is an increase of at least 400% compared to relying on third party solutions and manual installation".

Third party solutions (Nexus, 7DaysToDie.com) and manual installation ("where are the folders I need to put these mods in?").
Most 7 Days to Die players are not using mods, waiting for updates to use mods, or whatever. That is the most sensible deduction to make on the matter.
