This has been one personal pet peeve with the documentation surrounding Incus.
As a stack, Incus has been exceptional, it has largely replaced Proxmox and Podman Quadlets for me. For context, I homelab so I cannot generalize my claim to SMB or enterprise.
But the documentation has been very end user oriented, information regarding specifics like seccomp as you mentioned are only discoverable with the search bar and that leads to various disparate locations; and that also isn't taking into account that some of the more nitty gritty information isn't on the Incus portion of linuxcontainers.org, see the LXC Security page for example: https://linuxcontainers.org/lxc/security/
