While <strong>kernel bypass libraries</strong> and smart NICs have evolved, eBPF remains stuck serving infrastructure roles rather than complex services. This limitation exists because current <strong>verifier constraints</strong> and API restrictions force awkward splits between userspace logic and in-kernel execution, crippling performance for stateful applications.</p>
