What's the point in write-only register values?

What does the real hardware do here?

If the registers are writes-ignored, there's no need to store
the data written into the state struct; if the registers are
reads-as-written then implement them that way.

(If they get state struct fields the vmstate needs to be
updated accordingly, as does reset.)
