Generally such new features are gated by the negotiated fuse protocol version, which is a trade-off between supporting old systems & non-Linux OSes versus code complexity from handling multiple variants.

In an ideal world, with infinite resources (or at least, companies sponsoring the development!), we'd support everything, including the latest BPF trickery.
