I don't know about that.

As per my demonstrations, you can construct URLs for directly accessing
HTML docs that are scoped to specific schema.org entity types.

A page can only be about something. A CSE enables you access pages about
something that's an instance of one or more schema.org entity types.

A CSE isn't speaking to Google Crawlers. A CSE let's you scope queries
to Google's Index of Pages that include Structured Data Islands created
using Schema.org terms.

And I beg to differ since, "being there" to me is about the following:

[1] Incentivizing Web Masters and Web Developers to construct and
publish Web Documents that include both human and machine-comprehensible
Structured Data Islands

[2] Demonstrating utility of RDF Language based Structured Data, at
Web-scale

[3] Ending distractions such as RDF Language based Document Content
Format wars.
