If I wanted an organization policy that controlled when Friendly

find and distribute plug-ins to all of these products. As best
as I have been able to tell, no such plug-ins even exist for
Outlook and the other products do not accept extensions. There is
an opportunity here for valuable standardization.
The IETF has routinely punted, at least in the email space, on the
idea of prescribing or proscribing user interface behaviors because we
are protocol engineers, not human factors experts. Are you claiming
that's changed?
A 'friendly' amendment, or rather addition:
The origination side of an email exchange has no authority over
the reception side. Different administrative authorities. Compliance
with DMARC is voluntary -- and receiving administrations often implement
behaviors that differ from what is requested via DMARC.
There is no basis for believing that requests about MUA display
will achieve meaningful support on the receive side, nevermind whether
they would be at all useful.
