Correct.

If we make the operations variadic, the compiler can always
optimize (fx+ ...) into nested calls to dyadic lower-level primitives,
but this applies only to optimizations that the compiler knows about.
For user-defined inlinings, this is currently not possible.

No problem, you are very welcome.
