At IETF 119, we agreed that "by address" should be changed to something else in the ISA. The term "legacy ID" was used during the discussion but Christoph (if I remember right) pointed out that such IDs are not deprecated per se. Hence "legacy" may not be the right word since we use that word with legacy packet access instructions that are deprecated. We decided to take further discussion to the list, hence this email. We need some term to distinguish them from BTF IDs, so another alternative might be "non-BTF ID". Thoughts, or other alternatives? Dave
