Waldorf kindergartens don't have anything which resembles standard Prussian pedagogy. No desks, no assignments, none of that, and you aren't expected to read or write. It's mostly freeform play, we also learned to bake bread.
Everyone turned out fine. Rudolph Steiner has some, let's say idiosyncratic, theories of child development, but I think his basic thesis that children don't need to learn reading, writing, and maths, before their brains are ready for that information, is sound.
Kindergarten won't be to early for some children, but it will be too early for many. The ones it isn't too early for are just going to learn those things.
These kids are going to be fine, or more accurately, the damage will be from living through the global trauma, not from ordinary kindergarten being interrupted. I feel real compassion for the kids whose parents are forcing them to sit through Zoom school, though. To me it's clear this is the worst of the available options.
