Maybe useful for local chat conversation. But also to secretly check if someone is secretly nearby when you secretly crack the secret entrance to your secret base. Because really, who would use this for local chat?
You can do that already. You can switch to whatever channel you want to check and type /chat who It will tell you who can hear you in any channel you are currently in.
I always just do /c l /c who, but I'm lazy and don't like to type and also if for some reason they have you ignored that won't work.
+1 I almost lead, someone to my base with out knowing this and it isn't the first time u can just do /chat off and poof no1 knows u are there
I'm going to bump this. Doing /c l then /c who works, but it's not perfect. For example, a player could be ignoring you, have chat off, have hidden local chat, etc. A /near command would solve these problems.
