If the IETF wants to discourage top posting, write a mail markup that makes inline comments work reliably. I am sure the mail teams at Apple, Google and Microsoft would be interested. They probably spend much of their time dealing with vague interop.
In practice, that the teams wasted a lot of time trying to perform proper quotation for html text in vain is a perfect proof against using text/html for pointed discussion with properly quoted text. The problem is not an interop one between MUAs, because html structure depends on not only the MUAs but also end users, especially when the MUAs are powerful enough to let the end users control html structure in detail. In theory, it is well known that problems involving push down automaton are often unsolvable, which is likely to be the case. Thus, the reasonable thing to do for the teams is to abandon the effort, make plain text as their default e-mail service and shrink or disband.
