Not any more. The people suggesting it misunderstood what the PSL
contained. There are applications where only the ICANN part is useful but
DMARC is not one of them.
The performance issue is insignificant.
Maybe performance doesn't matter. However, what do we expect to find out by
a tree walk? We'd come to the same conclusion as using the ICANN only list
unless their record contains psd=y. Correct?
No, that is completely wrong. Please review the previous thousand
messsages about why we are switching to a tree walk.
