Indeed, and even so the tree walk gets the right answer nearly 100% of
the time, right now.

PSDs are rare, "abnormal" PSDs are even rarer.  The PSD tag is in arcane nit.

While I'm not opposed to the psd tags, I really wish people would get
some perspective. The amount of mail they affect is tiny, the amount
affected by uber-nits like whether a PSD can be an org domain is too
small to waste so much time on.
