Another example is hosted/native debug extension.

Need to scan the Server SoC requirements and identify the new SBI requirements that don't exist in the BRS.

Should we require support for hosted/native debug?

We may need FWFT, depending on what security features we require.

For now, I've created a PR with only SSE called out. We should discuss DBTR and FWFT more.

Merging the PR automatically closed this issue, but we may need to add more.
