Specifically, there are some domains (like .brand in my example) that
should be capable of being used as an organizational domain but are not
public suffixes themselves. This is exactly what "branded PSD" in
https://tools.ietf.org/html/draft-ietf-dmarc-psd-01#section-1 refers to.

Without this distinction, these domains don't make sense on a list of
public suffixes like the PSL. If we're going to have one list that
enumerate both public suffixes and public suffix domains, then this
distinction is critical for the branded PSD use case.
