Are polyhydroquinones considered to be polyphenols? Looking at the Wikipedia article for polyphenol, I was struck by how the monomer units shown are all substituted meta or ortho for the hydroxyl groups.

I assumed, naively, that polyhydroquinones would be considered polyphenols, but I am uncertain now. From what I can see, there is no IUPAC definition of polyphenols, so I am interested to know what commonly accepted criteria (and what contentious aspects, if any) are there for polyphenols.
The WBBSH definition states that polyphenols are defined as:


generally moderately water-soluble compounds
with molecular weight of 500–4000 Da
with >12 phenolic hydroxyl groups
with 5–7 aromatic rings per 1000 Da


This is the most widely accepted definition. However, due to the increase in research, there is a proposed Quideau definition stating

“The term "polyphenol" should be used to define compounds exclusively derived from the shikimate/phenylpropanoid and/or the polyketide pathway, featuring more than one phenolic unit and deprived of nitrogen-based functions.”

However, this is not an official definition (yet)
