Site Command That Shows Zero Supplemental Results

Did you know that if you wanted to ensure that zero supplemental results come up for a site command at Google, you can type your query in the syntax of site:www.example.com/*

I speculated over at Search Engine Land that Google Gearing Up To Drop The Supplemental Result Label. Is this one step towards that?

Tedster, WebmasterWorld administrator, added that "the site: command has been so flakey that I wonder what these many hack-type site: queries I read about actually return." However, he still finds this command fun and useful.

Reseller adds:

The following site: operator "version" shows results without supplemental

site:www.example.*

So is this truly removing the supplemental results or showing a subset of different results?
