We do try to use "extern" because it's nice documentation (and because
it visually matches the declarations of any non-function variables),
but for function declarations it really is nothing but documentation,
it has no actual technical meaning.

The compiler can see that it's a declaration and not a definition from
the lack of function body.

There's a number of other function declarations that don't have
"extern": the sha1 ones, some uemis ones, and at least some of the
dive planning ones. I wouldn't worry about it.
