As a final word: the elaborate trench networks like the German Hindenburg Line or the British positions around Arras, with concrete bunkers and dug-outs, multiple trench lines with firing bays and communication trenches, light railways bringing up ammunition to the gun positions, etc - these should certainly be represented by province fortifications. Such trench networks took months to build.
I do think attack and defense ratings need to modified to represent trench warfare. I think the West front trenches should be represented by fortifications, lower levels than say Verdun. The reason is that trench warfare was not the norm on the East front. In fact the East was somewhat mobile. Warfare in Russia, Rumania, Austria, and Turkey were not characterized by the high level of trench warfare there was on the West front. It was actually a lot more mobile front.
