That would make no sense. You can have multiple conns of which some but not
all share the same phase1. Why not display as much as possible? If you have
two sites with two tunnels each, totalling 4 conns, and 2 unique phase1's,
you do want the name to be one of the two, not some default name that could
be any of the 4.

I don't think it would cause less confusion. It would become harder to debug.
