Ye is really Þe (Þ = thorn) and it seems that printers, back in the day, used y instead, probably to save money. So it was probably considered old school when printing became popular and wasn't worth getting excited about.

Agricola means farmer in Latin, is that an incidental? You mention Lutherian, so perhaps an affectation.

Finnish W is inherently tied to Swedish W. Historically, V and W were the same letter, and they could be used interchangeably. W was generally preferred in Fraktur and V in Antiqua. In the 19th century, the orthography changed to use V everywhere, except in some proper names. This happened a bit earlier in Swedish than in Finnish. And, recently, V and W became separate letters. In 2006 in Swedish and (arguably) in 2022 in Finnish.
