 This document aims to address the use case of origination of TLS to backends from implementations.
 This is accomplished by a new `BackendTLSPolicy` API.
 
-This API solves the question "As an implementation, when I establish a connection to a backend, should I originate a TLS connection? If so, with what properties?"
+This API solves the question "As a Gateway API implementation, including Gateway For Mesh, when I establish a connection to a backend, should I originate a TLS connection? If so, with what properties?"
+
+!note: This TLS origination is NOT meant to impact mesh transport protocol, that often includes some kind of (m)tls. This means that for mesh, with (m)TLS enabled, this will mean double encryption. You can refer to more info in #non-goals
