Nothing new. If you have a compost toilet, you will have encountered spontaneous mushroom growth on your compost pile often enough. Also edible ones, like inkcaps. There is nothing against seeding it with a known mushroom kind. When you do that for your own household, you will know what diseases you have, and you get them anyway or are already resistant to them. Also know that the compost process kills any disease over time, and most diseases within days.
But I would never add a plastic, chemically poisoned diaper to my compost pile. Most modern diapers are chemical waste and need to be processed as such.
