Not that I don't have a problem with this, but has anyone attempted to make Docker/Moby support this filename by default too? Otherwise changing the filename creates a fair bit of annoyance for consuming them.

Changing the names that we use here is in scope. Changing the behavior of Docker is something else. We don't ship or use Docker in OCP or OKD.
