To be honest, this seems like you basically think "There are things I'd rather have so no", which is significantly more selfish than suggesting this idea.
Basically your counter of it is to use a third party program. And to use your own argument against you with the secret base thing
" you can just go to an abandoned channel, and tell your friend's to meet you there, and just use the normal chat, who's going to be around? It's essentially the same thing"
+1 To the idea though. It would be useful.
