I was just thinking the text should contain somewhere the word DMARC, this should be enough for bounce classifiers to figure it out

And in NetEase we use:

"550 MI:DMA $HostID, $TransID $now $Helplink\r\n"

As an example:
"550 MI:DMA mx1, M8CowEAJvEn_fs9P4xSCAA--.1493S3 1338998527 http://mail.163.com/help/help_spam_16.htm?ip=\r\n<http://mail.163.com/help/help_spam_16.htm?ip=>"

Is this something people think we should be standardizing?  It's pretty uncommon (read: I haven't seen it) to rely on specific content in the text part of an SMTP reply.  It might be interesting to compare, but I think I'm a bit itchy about the idea of requiring something specific in there.
