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.
