Yes.

Actually, there are circumstances where it's the right thing to do. 
Consider a daemon that has two listening sockets, one TCP socket for 
remote requests and one UNIX domain socket for local requests.  The 
daemon might want to treat these sockets differently, for security 
purposes perhaps, and the best way to distinguish them is via this 
key.

I'd recommend you treat this as follows:

o If you read an existing launchd property list, preserve these keys 
unless your client specifically changes one.

o If your client creates a new entry in Sockets, and doesn't 
explicitly specify a key, a reasonable default, like "Listeners", is 
fine.
