[dns-operations] Missing .us and GTLD records??

This is my first time posting, so please be gentle, this info has to do 
with GTLD delegations, specific to ".us"

So after registering some '.us' domains, I was using 'dig +trace' to 
verify the delegations got published on the GTLD servers.

Here is what I noticed, (you can repeat this, just pick any .us domain and 
run repeated 'dig +trace' for it)

It looks like there are missing .us GTLD records??

Something tells me this is not normal.

======================================
Sure enough,
You can confirm with plain old BIND, the "A" records do not exist, (just 
the glue, but not the A), should not all 'Registered Name Servers' have 
the 'A' records published, or am I totally wrong here.
