Yea, envoy is the premier open source (not open core+ paid features) proxy right now in my opinion. Modern, well supported, big community, reliable. If I was making a bet long term I would be looking at envoy and not some open core crap where they can rug pull you at any moment.
A whole bunch of the other ingress/k8s gateway offering also just…wrap envoy, so you may as well just use envoy directly these days. Especially given that configuring it, wasn’t any worse than configuring a wrapper with the additional benefit of not having anything between you and envoy to get in the way.
... Traefik is pretty good yes, but a standard? Hell no.
