Steve Singer suggests that perhaps we're "trying too hard" here.

Ensuring that, with *possibly* partial sets of paths, all nodes are getting all
events, may be pretty troublesome when considering the non-subscribing nodes.

The alternative is to consider that:

a) If the administrator set up a STORE PATH entry to indicate that node #1 can
pull data from node #3, then it is not unreasonable for the slon to use that
connection, as clearly intended.

b) If an administrator wishes to diminish the number of database connections,
they may readily do so by removing them (either by omitting STORE PATH, or by
submitting DROP PATH).  They may expect to benefit from there being fewer
database connections being opened.

c) There are times when additional paths will need to be added, such as at the
time of FAIL OVER.  Administrators are free to do so; it is expected to work
perfectly well, as long as the nodes are up.

We might improve our documentation to explain this.  Probably this would best
fit with the discussion of Listen Paths:
