The efficacy of the current specification is a continuing question among many
folk. Nonetheless, the From field is what it specifies.
And it seems that your concern relates to some other source of information.
Hence, not this specification.
The question issues by the Chairs is about naming of the current specification,
not some other possible spec.

And your preference for SSP remains a bit confusing, since that name has only
ever been applied to a version of the current specification and, hence, only to
using a value from the rfc2822.From field.

The word "Originator" refers to the combination of RFC2822 fields: From,
Sender, and Reply-to. That's 3 fields.

The word you are using is neither Originator nor From.
But that's not the word you are using. It's "sender".
hat term is commonly used for values ranging across rfc2822.From,
rfc2822.Sender, rfc2821.Received, rfc2821.MailFrom, rfc2821.Helo/Ehlo, and
client SMTP IP Address.
That rates as ambiguous.
