that sums it up neatly for me. I also think that adding complexity in
the free form at this stage may limit implementation and the numerous
ways in which it can be used for automation.

I see these quite similar to TXT records in DNS. and so, I do think that
at some point after this has been implemented, we'll need to document
widely adopted structures in a BCP.
