That doesn't seem helpful.  Each peer knows what it wants and it can initiate keep-alives based on its own needs.  Forcing the other peer to acquiesce doesn't add value.

Furthermore, you don't need a response, TCP provides ACKs.  A one-way exchange of as little as a single byte should be enough to keep any bindings alive in (TCP) intermediaries.

If you want to step a layer up to WebSocket intermediaries the ping concept works there.  I'm not convinced that this is necessary.
