You're comparing a third-level domain with a second-level XRI. That's
john.alford.smith.name and =john.alford.smith are roughly equivalent.
The benefit here is merely that you've replaced the ".name" with an
equals sign. Both have four "semantic units".
john.alford.smith.domain.tld would be more comparable to (for example)
@domain*john.alford.smith. Again, both of these have *five* of your
"semantic units", except that in this case a large number of domain
namespaces (.com, .org, .net and national variants on these) have been
collapsed into a single namespace identified by "@".
You can't really claim that the global context symbol is not a semantic
unit while counting the top-level domain as one. I put it to you that
you are attempting to mislead people.
(but not martin.atkins.name!)
