I would phrase that differently: Spam has a significant negative effect
on reliability of email. Spam filtering mitigates some of that, but is
not able to achieve 100% reliability.
Exactly right. 90-95% of the mail crossing the open Internet is spam.
The better receive-side filtering engines catch all but a very, very
small percentage of that.
I think it's worth considering whether IETF could improve this
situation via some combination of improved protocol and sound,
carefully-reviewed advice for implementors and/or operators.
I'm not optimistic there.

It's worth considering if and only if there are fresh and highly
pragmatic ideas driving the effort.
Given the number of years of anti-spam effort by intelligent,
experienced, and motivated people, and the number of times there have
been similar efforts to offer 'solutions', the likelihood of crossing
the threshhold of 'fresh and highly pragmatic' is low. Very low. But
low isn't (quite) zero.
