Not at all. If we can agree that lists should reject discardable

Refusing signups from those domains is probably a bit extreme,
though.
Providing immediate feedback regarding a domain likely to cause
recipients to miss their conversation should reduce the number of
subsequent support issues. Otherwise, lost conversations will likely
generate complaints requiring detailed analysis to resolve. Refusals
for either "all" or "discardable" when the list is known to invalidate
Author Domain signatures ensures list participants receive full
conversations.
If the recipient is rejecting mail from the list, then the list
should stop attempting to send mail to that recipient. It should not
try and guess why the mail is no longer wanted.
We really don't want people to use ADSP (or, much worse, DKIM) as an
excuse for not handling bounces nor for sending unwanted email.
The "discardable" assertion does NOT mean a mailing list will see
rejections. Only the "all" assertion ensures this level of feedback.
This is why it remains important to have "all" refused whenever
"discardable" is discarded. The concept of "discardable" was to offer
just this type of excuse.
