Thanks. Checked GCS Staging website. A few findings

e.g. the first graph states

I/O connectors denoted as Supported via Managed API can be accessed using the simplified managed I/O APIs for Java and Python.

We can add a link for [managed I/O APIs] to io/managed-io.md‎.

Consider add DeltaLakeIO to the Built-in I/O Connectors list
