We seem to rely on the behaviour that the "breaking changes" says now takes place, so I'm mildly confused what the breaking change really is, or whether we just thought we had configured those features and they didn't land until 7.0.0. But this seems OK to merge as-is. |

As the previous commit mentions, this does not occur on main, v1.16, and v1.15 due to cilium#29036. However, in v1.14 and v1.13, we need to take special care because the NameManager and SelectorCache lock can be taken while the Endpoint lock is held during Endpoint deletion. Here are the relevant stacktraces regarding the deadlock: ``` 1: sync.Mutex.Lock [75 minutes] [Created by http.(*Server).Serve in goroutine 1699 @ server.go:3086] sync sema.go:77

As the previous commit mentions, this does not occur on main, v1.16, and v1.15 due to cilium#29036. However, in v1.14 and v1.13, we need to take special care because the NameManager and SelectorCache lock can be taken while the Endpoint lock is held during Endpoint deletion. Here are the relevant stacktraces regarding the deadlock: ``` 1: sync.Mutex.Lock [75 minutes] [Created by http.(*Server).Serve in goroutine 1699 @ server.go:3086] sync sema.go:77
