There are very few F# specific features used in the book. I imagine you could follow along pretty easily with any other functional language. You can easily use F# for the book and then apply the lessons learned to another language when you're done too. It mainly shows how to use sum types, product types and function composition to implement DDD.
I'm not sure what tendencies you're referring to though. F# has been around for 20 years and has only gotten better over time.
