Counterpoint: I've had very few (and always minor) problems upgrading between major Fedora releases over the years with no more effort than following the well-documented steps to do so, including both traditional and atomic variants, the latter with a wide variety of layered packages as specifically not recommended due to potential problems when upgrading.

And on the server side of things, I ran a Fedora CoreOS VM with a Pihole container that silently and successfully auto-updated both the OS and the service container for years with no intervention on my part.
