Hi Klaus, Thank you. FYI, we considered those comments when editing draft-ietf-core-hop-limit-00. Early answers to these issues were made by Tiru at: https://mailarchive.ietf.org/arch/msg/core/giPOExiFuWDJdNtRY52g3dMkXAM. I do agree that (Allocating response code 5.06 for "Hop Limit Reached" is fine). We can suggest 5.06 when it comes to assigning TBA2 (during the IANA review process).
