Yes it is for the reasons you have stated before. If I run LISP from my house and obfuscate on EIDs, any eavesdropper can look at the source RLOC to determine I’m a Comcast customer (and can find out the head-end and tail-end connections - my house). That is a violation of my privacy. They can’t tell what transport connections I’m using and who I cam talking to but as long as the outer header is plaintext and “hidden aggreagated", it is a granular privacy invasion. If the LISP xTR was in Comcast, then it looks like some obfuscated EIDs are sending from Comcast. That doesn’t violate my personal privacy.

That is what I’m talking about.
