why does rsync translate user at host into '$RSYNC_RSH -l user host'?

Some of us ssh from random machines to other random machines.
Some ssh servers and clients are on appliances that are either 
impossible or completely impractical to configure ~/.ssh/* or don't even 
have any such thing as ~/.ssh/* in fact openssh is not even the only ssh 
server or client even when you are dealing with a unix-like system.

Configuring ~/.ssh/* is nice in some cases, and utterly impractical, or 
not even possible in others.

The OP's question was not about other ways to use ssh but why rsync 
couldn't allow the user to supply an unpredicted type of url that they 
happen to know would work if rsync would just not try to parse it but 
just collect it and and hand it off.
