To paraphrase Carl von Clausevitz, the enemy of a good XEP is the dream of
a perfect one.

The fact is that neither the proponents of a solution based around MAM, nor
those who insist there are serious flaws in Carbons as-is, have proposed

The above statement is absolutely crucial, since over the past few days the
only consistent feedback from the Myths wiki page concerning a concrete
missing feature in XMPP has been exactly this. We've had people even on

There is no other proposal on the table.
