why didn’t you build your own gateway from ground up? especially when rust runtime in envoy is not production ready yet. From envoyproxy,

… This extension is functional but has not had substantial production burn time, use only with this caveat.

This extension has an unknown security posture and should only be used in deployments where both the downstream and upstream are trusted.

Envoy has proven itself in the industry and we didn't want to reinvent the wheel by doing what envoy had already done for observability, rate-limits, connection management etc. And reason for using proxy-wasm was so we don't take hard dependency on any built version of envoy. There are many other benefits too which are listed here [1].

Regarding support for wasm runtime in envoy. We believe wasm support in envoy is not going anywhere and it will continue to become more and more stable over time. Envoy has heathy community and in case of any security vulnerability we will hope that envoy will ship fix quite fast which it has done in the past. See here for details of security patch rollout [2]
