This add-on is part of the presentation The Missing Camera or: How I Learned to Stop Worrying and Love Oblique Projection at BCON24.
The add-on is named after Karl Wilhelm Pohlke, author of a generalizing parallel projection theorem in 1853. The cover image is a detail of plate VIII "Palatin" from "L'art de bâtir chez les Romains" by Auguste Choisy (Ducher et Cie, Paris, 1873).
A paper has not yet been published on the add-on, but if you use it in your academic work you can cite it from Zenodo:

Big thanks to pioverfour for this contribution !

Exactly what I was looking for, it perfectly reproduces the traditional ortographic/isometric architectural projections. The only caveat: the correct result won't be visible in the viewports (you'll need to render the image)
