Friending Discord Bots

I was wondering if it would be possible to friend Discord bots. You could send a friend request to the bot (or contact the dev) and the developer could maybe "allow" the bot to be your Discord friend. 

I wanted to know because this way you could add bots to GCs because those are often more convenient than actual servers.

It would be really nice if there was an option to allow developers to allow people to friend their bots.

Thanks!
