Given the discussion in ITF LC/6man regarding EH insertion an modification, I think the aforementioned text shouldn't be there, or, at the very least, it should be made crystal-clear that EH insertion or modification violates current specs (RFC8200). Unfortunately, I haven't gone through this whole I-D, yet. BUt, when it comes to using EHs for anything, folks should be made aware about the issues related to RFC7872. Thanks!
