Eliot,
Perhaps it is better to explicitly deprecate multiple From lines?
As UIs have developed they really don't index well against
multiple From lines anyway.
...
In the end I stick with my preferred way forward: deprecate
multiple From lines.
The topic is not about multiple From header fields (lines),
these are prohibited by rfc2822 anyway. The topic is about
multiple author addresses in a single From header field.
