The patch is pretty trivial (minimal testing but don't see why it should not be stable). The value of $_ is saved and restored so you can change/use it in &wanted with impunity. Note as we are passing 3 values to the &wanted every time there will be a slowdown but this is probably (speculation) trivial compared to iterating over the directory tree.
