I don't know anyone who seeks to preserve this indistinction;
however, I know several folks who are realistic about the
difficulties of separating the two.

again, 'genetic purity' is a gloss over the real and significant
technical justifications for a global network address space -
many of which remain even if you do separate identify from network
location.
if you try to build a global network out of limited-scope addresses
you eventually end up reinventing IP at a higher layer.
