The receiver might read it as "sender doesn't care whether the 
mail gets delivered".

While there might be some domains that take that stance I wouldn't
expect "mainstream domains" to take that stance. I expect financial
institutions to be somewhat early adopters and any ISP/mailbox provider
that decides discardable means don't bother trying to deliver the mail
should be prepared to beef up their Customer Service staff to handle
complaints.

And beef up their legal retainers as well.

There is a significant difference between sendedr saying "I recognize
that a fraction of a percent of legitimate mail might not get delivered
if my assertion is followed" and "sender doesn't care whether the mail
gets delivered". 

+1.

I have less of an issue with the DISCARDABLE policy.

It is the lack of one or having the other policies with no handling 
semantics that will very interesting.  Same EMAIL abuse? Two different 
policies?  I see clear legal claims neglect against high-value domains 
who don't use DISCARDABLE.

In other words, if a receiver sees a damaging goods and continues to 
pass on the damaged goods because ASAP says so, and there is user harm, 
someone is going to be responsible.

This whole thing is ridden with fleas and the on-going administrator 
"myth" that there is no product liability risk with DISCARDING of MAIL, 
especially after issuing a 250 Acceptance.  It smacks against the 1986 
US EPCA provisions for satisfying "User Expectations."   The dynamic 
SMTP level reject satisfy this instant notification.  Accepting and 
discarding runs a HUGE risk.  So people better get this right.
