We may have found some domains that need a psd flag, but it's silly to assert we have found all or even most of them. The PSL has 9300 entries and there are surely far more places in the DNS than that where you want sibling domains to be separate. The PSL only cares about web cookies, which do not always separate at the same places that DMARC does. The PSL is often wrong for DMARC and I see no reason to assume that even without PSD that a tree walk would produce less accurate results than the PSL does. On the other hand, it is a whole lot easier to publish a psd=y DMARC record than to get an entry into the PSL so for anyone who cares about this, they have a straightforward way to fix their problems.
