Nit: any additional certificates contained as optional intermediates
=> intermediate certificates

You can add "any" to indicate that intermediate certificates
may not exist.

I.e., make this more concise, and use "intermediate CA certificates" or
"intermediate certificates" instead of
just "intermediates".
