It shouldn't, unless you're bypassing the actual protocol serialization layer (or hitting a bug in the implementation). Which is what's the case here. Protocol design can't address the case of users just writing out some bytes and declaring it's a valid protocol message.

I’m replying to a post where someone said most protocols have in-band signaling and therefore this problem is unavoidable.
