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.

Yes, thanks for the addition! I though about mentioning the link to Swedish W but wasn’t fully sure about the details.
