What's the point of a `readonly struct` if the types aren't implicitly made `readonly`?

What's the difference between a struct with ALL readonly fields, and a readonly struct, which requires you to explicitly state all fields as readonly?
This just seems like an extra KW for no reason, if it's not implicitly making things readonly.

Thanks!
Cheers!
