We seem to have a fairly basic disagreement of who "anyone" would be. 
I'm assuming, and I think the WG is assuming, that the audience for this 
document is people who are already somewhat familiar with SPF or DKIM or 
DMARC.  It appears that you believe it is possible to add enough 
mechanical detail that even someone who knows nothing about them could 
make these changes.  That seems awfully optimistic.

I don't fault you for not being an SPF or DKIM expert but I really don't 
think it is useful to add a lot of stuff that any plausible reader already 
knows.
