Hello,

Re-sending my reply as somehow the cc-fields got dropped when I posted
earlier.

This was the feedback received from the maintainers when I posted this
patch last year [1]. Accordingly, we updated the patch to drop
"output_pattern" altogether and made "output_type" read-only [2] -
haven't attempted upstreaming this version yet.

Thank you.

Guru Das.
