I'm not really sure what you mean, but unless I'm mistaking...

You usually want to add routes, the other end as the next hop.  If the
other end is not "connected", this is may be difficult.

As for theoretical reasons, I guess it would be enough just to be able to
declare arbitrary addresses "connected" to specified interfaces by adding
host routes if the implementation allows adding such for P-t-P links
without an explicit next-hop.
