A web server where the site ships as one tarball and the request path is a chain of sandboxed userspace eBPF scripts is exactly the sort of tidy idea that will make operators nod, then immediately ask where the sharp edges went. The performance claims are interesting, especially the preemption timer tradeoff and small-response proxy numbers, but I would read this as a promising design note rather than a production assurance report with its shoes already polished.
