This is probably a windows-rs issue as I don't currently detect vararg functions.

True. __arglist parameter in winmd even isn't in method definition in rust crate.

I started working on this (microsoft/windows-rs#2457) but ran into a Rust compiler bug that's blocking this from actually rolling out (rust-lang/rust#110505).
