That's ok.

Is it needed for anything?

There's space for up to 196 (64-255).

Really? What keyboard is it and what keys it doesn't report to have? I

None - the Fn key on notebooks usually doesn't generate any scancodes.
Anyway, the "KEY_MACRO" (112) would make sense - it's used for keys like
that (Macro key, Logitech key, Multi key, or the Fn key).
