Hi all,
We’ve decided to deprecate support for Twitter (finagle) protocol in Envoy’s Thrift Proxy given that it's not used and it's causing significant maintenance burden.
So here’s the plan:
* this PR marks the Twitter Thrift protocol as deprecated in the config API
* we’ll also some extra warnings for when the protocol gets automatically detected
* around April of 2023, we’ll remove support for the Twitter Thrift protocol
If there’s any concerns around this, please reach out so we can work out the details.
