Assuming your setup is a HWW with an offline PC used for verification that the seed was generated correctly, I would add that:
The PC should be completely wiped afterwards, in case it silently saved the rolls somewhere and is later connected online.
One should also verify that the correct private key was generated from the seed. Theoretically a HWW could display the correct seed but fall back on a malicious hardcoded private key.
