The outcome in either "except-mlist" or "all" remains beyond the

"except-mlist" is no worse here than "unknown", which is what the vast
majority of domains will be publishing in the absence of the
"except-mlist" option.
The sender benefits so let the senders do the work. A win-win for both
the sender and the recipient.
For most domains, the sender benefits are not sufficient to motivate a
"discardable" or TPA deployment.
And with neither TPA, "discardable" nor "except-mlist" in common use,
paying attention to ADSP isn't worth an MX admin's time. The sender loses
utterly.
