Where is there indication that this mechanism has been having operational problems?

Where is the discussion of an alternative?

Failing to obtain some history covering both of these questions, pursuing this topic doesn't seem likely to be productive, though it could be wonderfully expensive in time and frustration.

Some of us remember these things and the references are potentially useful to those who do.    Are we constrained to only talk about what we're sure everyone already knows?   I certainly don't want us to have to revisit the entire history of email in this discussion (and to have to repeat that discussion every few years), but I assume that people seriously involved in email are motivated to do that anyway.   So I don't think it's wrong to refer to history, and I think that sometimes it provides valuable context.

I doubt that much, if any, historical discussion should be in the 5321bis spec(s).   If someone really feels motivated there could be an informational document but I wouldn't want it to be a work item for a WG.
