When the --deployv option is used, the following message is shown:
Using --deployv option you will need to run the following extra step manually after to create the container or after running 20-run.sh script
docker exec -it --user=root CONTAINER find /home/odoo -maxdepth 1 -not -user odoo -exec chown -R odoo:odoo {} \;
AFAIK that message is no longer applicable, as the necessary permissions are now run by t2d itself, so the message should be removed.
If the message is still applicable, then I think it should be fixed.
