as Joseph pointed out, there is a different emulation strategy with a different failure mode (use link and potentially leave behind a hard-linked file under both names).
So far I haven't run into applications that prefer that strategy, i.e., nobody seems using that strategy on older kernels that don't support renameat2 with RENAME_NOREPLACE. If we run into enough apps that prefer this fallback, we could add a flag for it of course.
